A VOB file (DVD-Video Object) is a container format contained in DVD-Video media. It contains the actual Video, Audio, Subtitle and Menu contents in stream form.

VOB files are encoded very much like standard MPEG-2 files. If the extension is changed from .vob to .mpg or .mpeg, the file is still readable and continues to hold all information, although most MPEG-2-capable players don't support subtitle tracks.

In order to burn the VOB files to a DVD±R disc, other standard DVD-Video files are needed as well, including IFO and BUP files. The burning is easily done using software like Nero or Roxio Toast.

VOB files will play on a Macintosh using MPlayer, VLC media player, and sometimes DVD Player. [1] On a PC they will also play using VLC media player, Vidlizard, BSplayer, or Windows Media Player with ffdshow. On Linux, they will play using Xine and MPlayer.
