That's what I've used:

mencoder -ofps 25 -of lavf -lavfopts format=mp4 -af lavcresample=44100 
-vf-add harddup -vf-add scale=320:-11 -oac lavc -ovc lavc -lavcopts 
aglobal=1:vglobal=1:acodec=libfaac:abitrate=192:vcodec=libx264:vbitrate=384:keyint=25 
test.mp4 -o ipod.mp4

and that's the result - try if it'll works (6MB):
