Easiest solution, once you have it ripped to your hard disk with MtR is
to use MPEG Streamclip to open the first VTS segment of the VOB for the
movie in question. MPEGStreamclip will ask if you want just the one or
all segments loaded (you probably want "all"). Once Streamclip has the
whole thing loaded, choose the appropriate Demux command from the file
menu for the audio type present in your movie (you'll find this
information near the bottom of the Streamclip window) -- it's usually
AC3, i.e. Dolby Digital, and if it is, you'll need to convert it to a
format editable with QuickTime (I'd recommend AIFF as that will help
minimize the number of times the audio gets recompressed before you're
done).
