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.
