A DVD player has to be able to read a [[DVD]] in ISO – [[Universal Disk Format|UDF]] version 1.02 format, and needs to read and obey the DVDs [[Regional lockout]] codes and display a warning if the player is not authorized to play the DVD.

To play a DVD smoothly, it needs to be able to decode the [[MPEG-2]] video stream with a maximum [[bit rate]] of 10&nbsp;Mbit/s at peak and 8&nbsp;Mbit/s continuously.

A DVD player may be able to:
*Optionally decrypt the data with either [[Content-scrambling system|CSS]] and/or [[Macrovision]]
*Decode sound in [[MP2 (format)|MP2]], [[PCM]] or [[Dolby AC-3|AC-3]] format and output (with optional AC-3 to stereo downmixing) on stereo connector, optical or electric digital connector
*Output a video signal, either an analog one (in [[NTSC]] or [[PAL]] format) on the [[composite video|composite]], [[S-Video]], [[SCART]], or [[component video]] connectors, or a digital one on the [[DVI]] or [[HDMI]] connectors.
*Jump to manually entered titles, chapters, and time stamps.

DVD players cannot play [[Blu-ray]] discs due to using different wavelength lasers (Blu-ray discs use a blue-violet laser, hence their name, rather than a red laser). However, Blu-ray players are typically [[backwards compatible]], meaning they will play DVDs. Some are compatible with [[CD]] and other disc formats. The short-lived [[HD DVD]] format is also incompatible with DVD for the same reason, however, HD DVD players do play standard DVDs and CDs.

DVD players are largely controlled through a [[remote control]]. Built-in controls on the main unit's panel such as a [[D-pad|four-directional buttons]] vary depending on model. Some models may lack advanced built-in controls, making operation more dependent on the remote control.<ref>{{citation|title=GRUNDIG GDV 130 service manual […] }} (in comparison to ''[[Durabrand]] DV-100'')</ref>
