Recompresion only.

mencoder tea.mp4 -ovc lavc -oac lavc -lavcopts 
acodec=wmav2:vcodec=wmv2:keyint=25 -mc 0 -noskip -o test.avi

it's curucial that when using internal video codec to use internal audio 
codec as well, so it couldn't be "vcodec=mpeg4" and "acodec=libmp3lame" 
because it provides audio sync problems.
