>From looking at the source, it looks like a perfect rip just dumps the vob 
you select into a file. It should have all the audio and video information 
available, it largely just changes the extension from VOB and mpg. Just 
removing the extra audio isn't going to save you very much space. Your files 
are still going to be multigigabyte.

You should really consider sitting down some afternoon and playing with 
mencoder's multipass variable bitrate settings in xvid, and seeing if you 
can find something acceptable smaller, otherwise, there's really no point in 
bothering at all.

I haven't tested it myself, but this should work:

 tcextract -i movie.mpg -t vdr -x mpeg2 > movie.m2v
tcextract -i movie.mpg -a 128 -x ac3 -t vob > movie.ac3
mplex -f 8 -o movie2.mpg movie.m2v movie.ac3

It's just might not be worth the effort.

Of course, there could be a key detail in the DVDReading that I missed and 
you could end up with the exact same result as you started with. You'll have 
to have someone smarter than me tell you that,
