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,
