There is no -novideo for MEncoder, MEncoder must have a video stream 
to run. I'm not sure how 'mmg' works, but if it can accept input from 
avi's, you can use:

mencoder -o video.avi -nosound file.vob <encoding options>
mencoder -o audio1.avi -ovc frameno -mc 0 -noskip file.vob -aid 128 -oac copy
mencoder -o audio2.avi -ovc frameno -mc 0 -noskip file.vob -aid 129 -oac copy

and then merge as necessary.
