i've got a batch of wmv's provided that i'm trying to convert to xvid. 
the problem is, some of the wmv's work fine without -mc 0, and some need 
it.  when i use -mc 0 with the ones that work fine without, they lose 
a/v sync.

is there any way to get a reliable set of options that will always 
preserve wmv sync?

here's the command line i'm using:

$mencoder $in -o $in.mp4 -aspect 16:9 -of lavf -lavfopts 
format=psp:i_certify_that_my_video_stream_does_not_use_b_frames \
-oac lavc -ovc lavc -lavcopts 
-vf scale=374:214,crop=368:208:3:3,pp=fa,harddup -ofps 30
