mplayer -oac copy -ovc copy  -o x.avi -audiofile file.mp3 video.m4v

(works with mp2/1 audio, wav and few other formats too).
If audio is ac3 it is now automatically demuxed (based on the extension) 
by demux_lavf.
Other formats that are not automatically demuxed (such as aac) need

-audio-demuxer 20 -rawaudio format=0xyyyy:channels=n:bitrate=m:rate=w

BTW, muxer_lavf is beginning to work better: mpeg* and asf  (at least in 
my local tree)
produce valid and synced files.
