Ripping video from a video DVD:

Check the title (play title 4):

mplayer dvd://4 

It will also tell you the number of titles, chapters and other stats like frame rate (fps), bit rate (kbps), etc.

Rip DVD video:

• Re-encode DVD video to specified AVI:

  mencoder dvd://4 -ovc lavc -oac copy -o title4.avi

• Do not re-encode DVD video (just dump):

  mplayer -dumpstream dvd://4 -dumpfile title4.mpeg

  • (DVD original quality video. The penalty is the much larger file size.)
    
  • This is the same as cp /media/cdrecorder/VIDEO_TS/VTS_01_1.VOB title1.mpeg
    
  • The DVD “VOB” file typically is an MPEG (I or II) video although all variations are not allowed.
    
  • Full video and sound are captured. The DVD video format allows for multiple language sound tracks thus copying a movie released in multiple languages may have surprising audio results.
