==TiVo digital video recorder==
{{main|TiVo digital video recorders}}
A TiVo DVR serves a function similar to that of a [[videocassette recorder]] (VCR), in that both allow a TV viewer to record programming for viewing at a later time, known as [[time shifting]]. Unlike a videocassette recorder, which uses removable magnetic tape cartridges, a TiVo DVR stores TV programs on an internal hard drive, much like a computer.

A TiVo DVR also automatically records programs that the user is likely to be interested in. TiVo DVRs also implement a patented feature that TiVo calls "trick play", allowing the viewer to pause live television and rewind and replay up to 30 minutes of recently viewed TV. TiVo DVRs can be connected to a computer local area network, allowing the TiVo device to download information, access video streaming services such as [[Netflix]] or [[Hulu]], as well as music from the Internet.

===Functions===
TiVo DVRs communicate with TiVo's servers on a regular basis to receive program information updates, including description, regular and guest actors, directors, genres, whether programs are new or repeats, and whether broadcast is in High Definition (HD). Information is updated daily into its program guide from Rovi ([[Tribune Media Services]] was used prior to September 2016<ref name="Engadget 2016">{{cite web | title=TiVo is pulling the plug on Series 1 DVRs September 29th | website=Engadget | date=2016-08-16 | url=https://www.engadget.com/2016-08-16-tivo-series1-lifetime-over.html | access-date=2021-05-24 | archive-date=May 24, 2021 | archive-url=https://web.archive.org/web/20210524220424/https://www.engadget.com/2016-08-16-tivo-series1-lifetime-over.html | url-status=live }}</ref>).

Users can select individual programs to record or a "OnePass" (formerly "Season Pass") to record all episodes of a show. There are options to record First Run Only, First Run and Repeats, or All Episodes. An episode is considered "First Run" if aired within two weeks of that episode's initial air date. OnePasses can also "bookmark" shows from internet streaming video services and show a combined view of recordings and bookmarks.

When users' requests for multiple programs are conflicting, the lower priority program in the OnePass Manager is either not recorded or clipped where times overlap. The lower priority program will be recorded if it is aired later. TiVo DVRs with multiple tuners simultaneously record the top priority programs.

TiVo pioneered recording programs based on household viewing habits;<ref>{{Cite news |last1=Wingfield |first1=Nick |last2=Saranow |first2=Jennifer |date=February 9, 2004 |title=TiVo Tunes In To Its Users' Viewing Habits |work=The Wall Street Journal |url=https://www.wsj.com/articles/SB107627909024923840?mod=_newsreel_5 |access-date=May 6, 2022 |archive-date=May 6, 2022 |archive-url=https://web.archive.org/web/20220506141718/https://www.wsj.com/articles/SB107627909024923840?mod=_newsreel_5 |url-status=live }}</ref> this is called TiVo Suggestions. Users can rate programs from three "thumbs up" to three "thumbs down". TiVo user ratings are combined to create a recommendation, based on what TiVo users with similar viewing habits watch. For example, if one user likes ''[[American Idol]]'', ''[[America's Got Talent]]'' and ''[[Dancing with the Stars]]'', then another TiVo user who watched just ''American Idol'' might get a recommendation for the other two shows. As of 2023, Tivo Suggestions are no longer supported. The Thumbs Up/Down buttons can no longer be used to rate programs.

The amount of storage capacity for programs is dependent upon the size of the hard drive inside the TiVo; different models have different sized hard drives. When the space is full on the hard drive, the oldest programs are deleted to make space for the newer ones; programs that users flag to not be deleted are kept and TiVo Suggestions are always lowest priority. The recording capacity of a TiVo HD DVR can be expanded with an external hard drive, which can add additional hours of HD recording space and standard definition video recording capacity.

When not recording specific user requests, the current channel is recorded for up to 30 minutes. Dual-tuner models record two channels. This allows users to rewind or pause anything that has been shown in the last thirty minutes&nbsp;— useful when viewing is interrupted. Shows already in progress can be entirely recorded if less than 30 minutes have been shown. Unlike VCRs, TiVo can record and play at the same time. A program can be watched from the beginning even if it is in the middle of being recorded, which is something that VCRs cannot do. Some users take advantage of this by waiting 10 to 15 minutes after a program starts (or is replayed from a recording), so that they can fast forward through [[Television advertisement|commercials]]. In this way, by the end of the recording viewers are caught up with live television.

Unlike most DVRs, TiVo DVRs are easily connected to [[home network]]s,<ref>{{cite web|url=http://www.tivo.com/mytivo/howto/getconnected/howto_connect_dvr_internet.html|title=How to connect your TiVo DVR to your network and the Internet|website=Tivo.com|access-date=October 31, 2008|archive-url=https://web.archive.org/web/20081025010359/http://www.tivo.com/mytivo/howto/getconnected/howto_connect_dvr_internet.html|archive-date=October 25, 2008|url-status=dead}}</ref> allowing users to schedule recordings on TiVo's website (via TiVo Central Online), and transfer recordings between TiVo units (Multi-Room Viewing (MRV)). Former and now discontinued features included the ability transfer recordings to and from a home computer (TiVoToGo (TTG) transfers), play music and view photos over the network, and access third-party applications written for TiVo's Home Media Engine (HME) API.

TiVo added a number of broadband features, most of which are no longer offered. These include:

Integration with Amazon Video on Demand, Jaman.com<ref>{{cite web|url=http://www.tivo.com/abouttivo/pressroom/pressreleases/2008/pr2008-10-23.html|title=TiVo Joins with Jaman to Deliver the Best of the Big Screen to Living Rooms Across the Country|website=Tivo.com|access-date=November 1, 2008|archive-url=https://web.archive.org/web/20081122143512/http://www.tivo.com/abouttivo/pressroom/pressreleases/2008/pr2008-10-23.html|archive-date=November 22, 2008|url-status=dead}}</ref> and Netflix Watch Instantly,<ref>{{cite web|url=http://www.tivo.com/abouttivo/pressroom/pressreleases/2008/pr2008-10-30.html|title=TiVo and Netflix Announce Partnership|website=Tivo.com|access-date=October 31, 2008|archive-url=https://web.archive.org/web/20081102110457/http://www.tivo.com/abouttivo/pressroom/pressreleases/2008/pr2008-10-30.html|archive-date=November 2, 2008|url-status=dead}}</ref> offering users access to thousands of movie titles and television shows right from the comfort of their couch. Additionally, broadband connected to TiVo boxes can access digital photos from Picasa Web Albums or Photobucket. Another popular feature is access to Rhapsody music through TiVo, allowing users to listen to virtually any song from their living room. TiVo also teamed up with One True Media to give subscribers a private channel for sharing photos and video with family and friends. They can also access weather, traffic, Fandango movie listings (including ticket purchases), and music through Live365. In the summer of 2008 TiVo announced the availability of YouTube videos on TiVo.

On June 7, 2006, TiVo began offering TiVoCast, a broadband download service that initially offered content from places such as Rocketboom or, The New York Times; now there are over 70 TivoCast channels available for TiVo subscribers.

In January 2005, TiVoToGo, a feature allowing transfer of recorded shows from TiVo boxes to PCs, was added. TiVo partnered with Sonic in the release of MyDVD 6.1, software for editing and converting TiVoToGo files. In January, 2007, TiVoToGo was extended to the [[Macintosh]] with Toast Titanium 8, Roxio software for assembly and burning digital media on CD and DVD media. In August, 2005, TiVo rolled out "TiVo Desktop" allowing the copying of MPEG2 video files from PCs to TiVo for playback by DVR. As of June 5, 2013, TiVo stopped distributing the free version of TiVo Desktop for PC in favor of selling TiVo Desktop Plus.<ref>[http://support.tivo.com/app/answers/detail/a_id/2675/kw/desktop] {{dead link|date=March 2019}}</ref> Users who previously downloaded the free version of TiVo Desktop could continue to use the software without paying a fee for the Plus edition.

;Parental features
TiVo KidZone (later removed in the Premiere and Roamio devices) was designed to give parents greater control over what their children see on television. This feature allows parents to choose which shows their children can watch and record. It also helps kids discover new shows through recommendations from leading national children's organizations. TiVo KidZone provides a customized Now Playing List for children that displays only pre-approved shows, keeping television as safe as possible.

===Subscription service===
The information that a TiVo DVR downloads regarding television schedules, as well as software updates and any other relevant information is available through a monthly service subscription in the United States. A different model applies in Australia, where the TiVo media device is bought for a one-off fee, without further subscription costs.

;Lifetime subscription
There are multiple types of Product Lifetime Service. For satellite-enabled TiVo DVRs, the lifetime subscription remains as long as the account is active; the subscription does not follow a specific piece of hardware. This satellite lifetime subscription cannot be transferred to another person. Toshiba and Pioneer TiVo DVD recording equipped units include a "Basic Lifetime Subscription", which is very similar to Full Lifetime, except only three days of the program guide are viewable; and search and Internet capabilities are not available, or at least are limited. All units (except satellite but including DVD units) can have "Product Lifetime Subscription" added to the TiVo service, which covers the life of the TiVo DVR, not the life of the subscriber. The Product Lifetime Subscription accompanies the TiVo DVR in case of ownership-transfer. TiVo makes no warranties or representations as to the expected lifetime of the TiVo DVR (aside from the manufacturer's Limited Warranty). In the past TiVo has offered multiple "Trade Up" programs where you could transfer the Product Lifetime Subscription from an old unit to a newer model with a fee. A TiVo can be used without a service-agreement, but it will act more like a VCR in that you can only perform manual recordings and the TiVo can't be connected to the TiVo service for local time, program guide data, software updates, etc. or TiVo will shut down the recording function.

====Service availability====
The TiVo service is available in the United States, United Kingdom, Canada, Mexico, Spain and Taiwan at present. Over the years since its initial release in the United States, TiVo Series1 and Series2 DVRs have also been modified by end users to work in Australia, Brazil, Canada, New Zealand, the Netherlands, and South Africa.

TiVo went on sale in New Zealand in the first week of November 2009.<ref name="Sticking point for TiVo"/>

The TiVo Service came to an end in Australia on 31 October 2017.<ref>{{cite web|url=https://www.mytivo.com.au/|archive-url=https://web.archive.org/web/20171101105346/https://www.mytivo.com.au/|url-status=dead|archive-date=2017-11-01|title=TiVo Service closed in Australia|website=Mytivo.vom.au}}</ref> The electronic programming guide and TiVo recording features are no longer available, thus making all TiVo machines in Australia virtually useless.

=====United Kingdom=====
The TiVo service was launched in the United Kingdom in the autumn of 2000. It sold only 35,000 units over the next 18 months. Thomson, makers of the only UK TiVo box, abandoned it in early 2002 after [[BSkyB]] launched its [[Sky+]] integrated "set-top" decoder and DVR, which dominated the market for DVRs in homes subscribing to BSkyB's paid-for satellite television service. Many manufacturers, including Thomson<ref>[http://www.pvruk.co.uk/article.cfm?attributes.article=596 ''Freeview/Freeview Playback/Satellite/Cable'', PVR UK website, Undated] {{Webarchive|url=https://web.archive.org/web/20080528233824/http://www.pvruk.co.uk/article.cfm?attributes.article=596 |date=May 28, 2008 }}.Accessed: 04-30-2008.</ref><ref>[http://www.freeview.co.uk/products/dtrrange-page ''Latest Range'' Freeview website, Undated] {{Webarchive|url=https://web.archive.org/web/20080508045853/http://www.freeview.co.uk/products/dtrrange-page |date=May 8, 2008 }}.Accessed:04-30-2008.</ref> have launched integrated decoder boxes/DVRs in the [[United Kingdom|UK]] for other digital platforms, including [[Freesat|free satellite]], [[Freeview (UK)|terrestrial]], [[Virgin Media|cable]] and [[Tiscali TV (UK)|IPTV]].

A technical issue caused TiVo Suggestions to stop recording for S1 UK TiVo customers in late September 2008, but this was fixed in late January 2009.<ref>[http://www.tivocommunity.com/tivo-vb/showthread.php?t=406543 ''TiVo Suggestions in the UK&nbsp;— Update'', TiVo Community Forum, 09-29-2008] {{Webarchive|url=https://web.archive.org/web/20081002183904/http://www.tivocommunity.com/tivo-vb/showthread.php?t=406543 |date=October 2, 2008 }}.Accessed: 1 November 2008.</ref>

Since December 2010, UK TiVo units that were not already on an active monthly subscription or lifetime subscription could no longer be re-activated. BSkyB who were operating the support for TiVo no longer had full access to the TiVo systems to activate accounts.{{Citation needed|date=May 2018}}

The TiVo S1 subscription service was maintained for both lifetime and monthly subscriptions until 1 June 2011.<ref>{{cite web|url=http://blog.tivo.com/2011/02/1123/|title=''TiVo Blog''|website=Blog.tivo.com|access-date=February 16, 2011|archive-url=https://web.archive.org/web/20110218063931/http://blog.tivo.com/2011/02/1123/|archive-date=February 18, 2011|url-status=dead}}</ref> A community project known as AltEPG was established in March 2011 with the aim of providing a replacement for the discontinued subscription service.

On 24 November 2009, cable television provider [[Virgin Media]] entered into a strategic partnership with TiVo.<ref name="Virgin Media Selects Tivo">{{cite web|url=http://pressoffice.virginmedia.com/phoenix.zhtml?c=205406&p=irol-newsArticle&ID=1359213&highlight=|title=Virgin Media Selects Tivo For Next Generation Tv Platform|publisher=Virgin Media|date=24 November 2009}}{{Dead link|date=August 2019 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> Under the mutually exclusive agreement, TiVo developed a converged television and broadband interactive interface to power Virgin Media's next generation, high definition set top boxes.

===Hardware anatomy===
{{Main|TiVo DVRs}}
[[Image:Tivo-remote.jpg|thumb|200px|The TiVo "peanut" remote]]
The TiVo DVR was designed by TiVo Inc., which currently provides the hardware design and [[Linux]]-based TiVo software, and operates a subscription service (without which most models of TiVo will not operate). TiVo units have been manufactured by various [[Original equipment manufacturer|OEM]]s, including [[Philips]], [[Sony]], [[Cisco]], [[Hughes Electronics|Hughes]], [[Pioneer (company)|Pioneer]], [[Toshiba]], and [[Humax]], which license the software from TiVo Inc. To date, there have been six "series" of TiVo units produced.

TiVo DVRs are based on [[PowerPC]] (Series1) or [[MIPS architecture|MIPS]] (Series2) processors connected to [[MPEG-2]] encoder/decoder chips and high-capacity [[Advanced Technology Attachment|IDE/ATA]] hard drives. Series1 TiVo units used one or two drives of 13–60 GB; Series2 units have drives of 40–250 GB in size. TiVo has also partnered with [[Western Digital]] to create an external hard drive, the My DVR Expander, for TiVo HD and Series3 Boxes. It plugs into the TiVo box using an [[eSATA]] interface. It expands the High-Definition boxes by up to 67 hours of HD, and around 300 hours of standard programming. Other TiVo users have found many ways to expand TiVo storage, although these methods are not supported by TiVo, and may void the warranty.

Some recent models manufactured by Toshiba, Pioneer, and Humax, under license from TiVo, contain [[DVD-R]]/[[DVD-RW|RW]] drives. The models can transfer recordings from the built-in hard drive to DVD Video compliant disc, playable in most modern DVD systems.

Most standalone TiVo DVRs have [[Coaxial cable|coax]]/RF-in and an internal cable-ready tuner, as well as analog video input&nbsp;— composite/RCA and S-Video, for use with an external cable box or satellite receiver. The TiVo unit can use a serial cable or [[infrared blaster]]s to control the external receiver. They have coax/RF, composite/RCA, and S-Video output (newer models have HDMI output for video and audio), and the DVD systems also have component out. Audio is RCA stereo, and the DVD systems also have digital optical out.

Until 2006, standalone TiVo systems could only record one channel at a time, though a dual-tuner Series2DT (S2DT) box was introduced in April 2006. The S2DT has two internal cable-ready tuners and it supports a single external cable box or satellite receiver. The S2DT is therefore capable of recording two analog cable channels, one analog and one digital cable channel, or one analog cable and one satellite channel at a time, with the correct programming sources. Note, however, that the S2DT, unlike earlier units, cannot record from an antenna. This is due to an [[Federal Communications Commission|FCC]] mandate that all devices sold after March 2007 with an [[NTSC]] tuner must also contain an [[ATSC tuner]]. TiVo therefore had to choose between adding ATSC support, or removing NTSC support. With the S2DT they opted to remove NTSC; the Series3 supports NTSC and ATSC, along with digital cable channels (with CableCards).

The Series2 DVRs also have [[Universal Serial Bus|USB]] ports, currently used only to support network (wired [[Ethernet]] and [[WiFi]]) adapters.<ref>{{cite web |url=http://www.tivo.com/adapters |title=List of compatible adapters |website=Tivo.com |access-date=October 16, 2012 |archive-url=https://web.archive.org/web/20120826115430/http://www.tivo.com/adapters/ |archive-date=August 26, 2012 |url-status=dead }}</ref> The early Series2 units, models starting with 110/130/140, have USB1.1 hardware, while all other systems have USB2.0. There have been four major generations of Series2 units. The TiVo-branded 1xx and 2xx generations were solid grey-black. The main difference was the upgrade from USB&nbsp;1.1 to the much faster USB&nbsp;2.0. The 5xx generation was a new design. The chassis is silver with a white oval in the faceplate. The white oval is [[backlight|backlit]], leading to these units being called "Nightlight" boxes. The 5xx generation was designed to reduce costs, and this also caused a noticeable drop in performance in the system menus as well as a large performance drop in network transfers. The 5xx generation also introduced changes in the [[booting|boot]] [[Programmable read-only memory|PROM]] that make them unmodifiable without extensive wiring changes. The 6xx generation resembles the previous 5xx model, except that it has a black oval. The 6xx is a new design and the only model available today is the S2DT with dual tuners and a built-in 10/100baseT Ethernet port as well. The 6xx is the best performing Series2 to date, outperforming even the old leader, the 2xx, and far better than the lowest performing 5xx.

Some TiVo systems are integrated with [[DirecTV]] receivers. These "DirecTiVo" recorders record the incoming [[satellite]] MPEG-2 digital stream directly to hard disk without conversion. Because of this and the fact that they have two tuners, DirecTiVos are able to record two programs at once. In addition, the lack of digital conversion allows recorded video to be of the same quality as live video. DirecTiVos have no MPEG encoder chip, and can only record DirecTV streams. However, DirecTV has disabled the networking capabilities on their systems, meaning DirecTiVo does not offer such features as multi-room viewing or TiVoToGo. Only the standalone systems can be networked without additional unsupported [[Hack (technology slang)|hacking]].

DirecTiVo units (HR10-250) can record HDTV to a 250 GB hard drive, both from the DirecTV stream and [[terrestrial television|over-the-air]] via a standard [[ultra high frequency|UHF]]- or [[very high frequency|VHF]]-capable antenna. They have two virtual tuners (each consisting of a DirecTV tuner paired with an ATSC over-the-air tuner) and, like the original DirecTiVo, can record two programs at once; further, the program guide is integrated between over-the-air and DirecTV so that all programs can be recorded and viewed in the same manner.

In 2005, DirecTV stopped marketing recorders powered by TiVo and focused on its own DVR line developed by its business units. DirecTV continues to support the existing base of DirecTV recorders powered by TiVo.

On 8 July 2006, DirecTV announced an upgrade to version 6.3 on all remaining HR10-250 DirecTiVo receivers, the first major upgrade since this unit was released. This upgrade includes features like program grouping (folders), a much faster on-screen guide, and new sorting features.

In September 2008, DirecTV and TiVo announced that they have extended their current agreement, which includes the development, marketing and distribution of a new HD DIRECTV DVR featuring the TiVo service, as well as the extension of mutual intellectual property arrangements.

Since the discontinued Hughes Electronics DirecTV DVR with TiVo model HR10-250, all TiVo units have been fully HDTV capable. Other TiVo models will only record analog standard definition television (NTSC or [[PAL]]/[[SECAM]]). The Series3 "TiVo HD, and TiVo HD XL" DVRs and the Series4 "TiVo Premiere and TiVo Premiere XL" DVRs are capable of recording HDTV both from antenna (over the air) and cable (unencrypted QAM tuner or encrypted with a Cable Card) in addition to normal standard definition television from the same sources. Unlike the HR10-250, neither the Series3 nor Series4 units can record from the DirecTV service; conversely, the HR10-250 cannot record from digital cable. Other TiVo models may be connected to a high definition television (HDTV), but are not capable of recording HDTV signals, although they may be connected to a cable HDTV set-top box and record the down-converted outputs.

In 2008, some cable companies started to deploy [[switched digital video]] (SDV) technology, which initially was incompatible with the Series3 and TiVo HD units. TiVo Inc worked with cable operators on a tuning-adapter with USB connection to the TiVo to enable SDV. Some [[Multiple system operator|MSOs]] now offer these adapters for free to their customers with TiVo DVRs.

===Drive expansion===
TiVo has partnered with [[Western Digital]] to create an external hard drive, the My DVR Expander eSATA Edition, for TiVo HD and Series3 systems. The external drive plugs into the TiVo box using an [[eSATA]] interface. The first version of the eSATA drive shipped was a 500 GB drive that shipped in June 2008. In June 2009 the 1 TB version of the drive began shipping. The 1 TB version expands the TiVo HD and Series3 systems' capacity by up to 140 hours of HD content or 1,200 hours of standard programming.

TiVo was not designed to have an external drive disconnected once it has been added, because data for each recording is spread across both the internal and external disk drives. As a result, it is not possible to disconnect the external drive without deleting content recorded after the external drive was added. If disconnected, any recordings made will not be usable on either the internal or external drives. However, the external drive may be removed (along with content) without losing settings.

Various capacities of external drives have been shipped since the product was initially released. There were reports of product reliability issues,<ref>{{cite web|url=http://support.tivo.com/app/answers/detail/a_id/308|archive-url=https://archive.today/20120721221941/http://support.tivo.com/app/answers/detail/a_id/308|url-status=dead|archive-date=2012-07-21|title=TiVo support for DVR Expander problems|website=Support.tivo.com}}</ref> and a brief period of unavailability.<ref>{{cite web|url=http://www.tivo.com/dvr-products/tivo-accessories/extra-dvr-storage/index.html#A00096|title=TiVo Website showing 1TB drive and stock status|website=Tivo.com|access-date=February 16, 2010|archive-url=https://web.archive.org/web/20100302154516/http://www.tivo.com/dvr-products/tivo-accessories/extra-dvr-storage/index.html#A00096|archive-date=March 2, 2010|url-status=dead}}</ref>

The Western Digital 1 TB and 500 GB My DVR Expander eSATA Edition and My DVR Expander USB Edition drives have been discontinued and replaced with the Western Digital My Book AV DVR Expander 1 TB drive. This drive has received a facelift from the previous generation, which now sports a glossy finish, and a tiny white LED power indicator, along with a push button power switch in the back. The biggest change is that this drive now includes both eSATA and USB in one device. This device is DirectTV, Dish Network, TiVo, Moxi, Pace, and Scientific Atlanta (Cisco) certified. Seagate has come out with their own DVR-oriented drive called the Seagate GoFlex DVR which comes in a 1 TB and 2 TB capacity.<ref>{{Cite web|title = The page is no longer available.|url = http://www.wdc.com/en/company/releases/PressRelease.asp?release=bcd696a6-dddd-446e-b1e8-9113722c4f75|website = www.wdc.com|access-date = 2016-01-02|url-status = dead|archive-url = https://web.archive.org/web/20100702064720/http://www.wdc.com/en/company/releases/PressRelease.asp?release=bcd696a6-dddd-446e-b1e8-9113722c4f75|archive-date = July 2, 2010}}</ref> TiVo has not approved the Seagate product for use with TiVo DVRs and they will not currently function with any TiVo products.<ref>[http://tivoproduction.force.com/Support/articles/Troubleshooting/DVR-Expander-Troubleshooting/] {{dead link|date=March 2019}}</ref>

===Hacking===
Users have installed additional or larger hard drives in their TiVo boxes to increase their recording capacity. Others have designed and built [[Ethernet card]]s<ref>{{cite web|last1=Tridgell|first1=Andrew|title=tivo-ethernet isa_adapter|url=https://www.samba.org/~tridge/tivo-ethernet/|access-date=2 January 2016|archive-url=https://web.archive.org/web/20141006030438/http://www.samba.org/~tridge/tivo-ethernet/|archive-date=October 6, 2014|url-status=dead}}</ref> and a [[Web interface]] ([[Tivoweb|TiVoWeb]]), and figured out how to extract, insert and transfer video among their TiVo boxes. Other hacks include adding time to the start and end of recording intelligently<ref>{{cite web|last=Anderton|first=Stuart|title=Automatic soft padding running on the TiVo|url=http://www.tivocommunity.com/tivo-vb/showthread.php?t=136658|access-date=December 15, 2013|archive-url=https://web.archive.org/web/20131215201459/http://www.tivocommunity.com/tivo-vb/showthread.php?t=136658|archive-date=December 15, 2013|url-status=dead}}</ref> and sending daily e-mails of the TiVo's activity.

TiVo still uses the same encoding, however, for the media files (saved as .TiVo files). These are MPEG files encoded with the user's Media Access Key (MAK). However, software developers have written programs such as tivodecode and tivodecode Manager to strip the MAK from the file, allowing the user to watch or send the recordings to friends.
