I also use mencoder to create an avi that is split by mencoder and  
muxed to an mp4 with mp4creator.  To dump the audio, I use:
mplayer input.avi -dumpaudio -dumpfile audio.aac

Which should dump the audio faster than real time.  Likewise, I use:
mplayer input.avi -dumpvideo -dumpfile blah.h264

for the video.
