[AAR.oner]

i'm a little rusty when it comes to PC ish, but i believe you can demux [split the vob's audio and video] using DVD Shrink...there was also a prog called Virtual Dub that can do it as well...ya might try searching over at videohelp.com using the key word "demux"...

as to the actual steps of the process, hopefully one of the PC authorers will be able to give you some more details
