You shouldn't use the VOBs directly. Is better to "play de DVD". You can
use MENCODER to repack the DVD video and audio without recompressing it
(and, of course, without quality loss). The trick is to use the "copy"
codec:

mencoder -oac copy -aid 1 -ovc copy -of mpeg -mpegopts format=dvd:tsaf
- -o OUTPUT_FILE.MPG dvd://DVD_TRACK

replacing OUTPUT_FILE.MPG with the file name you want as output, and
DVD_TRACK with a number, to specify the track to repack (remember that
menus are tracks too).

When you have it repacked, use FFMPEG2THEORA to convert it.
