  Video DVDs have specific video-file formats that can be read by a conventional DVD player. These video formats are encoded with specific codecs and containers. If a video is not in the correct format when burned to a DVD, it will not be playable on a standard DVD player. Many software packages are available to transcode video files into the correct DVD video format.
  
  

MPEG-2

• MPEG-2, which stands for the Moving Pictures Expert Group, Standard 2, is the standard video file supported by all commercial DVD players and is the video format used for all non-Blu-Ray DVDs both in the United States and internationally. A DVD MPEG-2 file must be encoded at a resolution of 720x480 or 704x480 with a frame rate of either 23.076, 25 or 29.97 for NTSC DVD players.
  
  

VOB

• A VOB file, also known as a Video Object, is a video file that compresses an MPEG 2 video stream together with separate audio, subtitle and DVD menu streams. These compressed streams are then cut into smaller video objects, so that the single large VOB becomes a series of sequentially named smaller VOB files. VOB files can be burned directly to any DVD with any DVD-burning software.
  
  

MPEG-TS

• MPEG-TS, also known as an MPEG Transport Stream, is an MPEG-2 video file that results from some DVR and video-capture software. Because cable TV is streamed in the same MPEG-2 format that DVDs use, a video recorder using a analog capture device will be DVD ready with the exception of the format. An MPEG-TS will need its format to be changed from Transport Stream, which ends with the extension .ts, to a generic .mpeg extension that a DVD player can read. Otherwise, an MPEG-TS is DVD ready and can be easily transferred to a DVD.
