Yup.

I use -dumpvideo and -dumpaudio to dump the video/audio stream I want, 
then use mplex (part of mpeg-tools) to put them back together into a new 
vob.

mplayer devs will be quick to point out that -dumpvideo and -dumpaudio 
are for testing purposes only and should not be used this way, but it 
just happens to work well with simple mpeg files.  I think the correct 
way to do this otherwise would be to use mncocder with -oac and -ovc 
options set to copy

You can also use VLC to dump a stream with just the audio/video track 
you want.
