As I hear tell, ffmpeg's mpeg encoders suck.  But you must remember, 
that encoding wmv (actually just asf in a wmv container, and not an 
acual wmv codec) is a lot different than mpeg.  you're likely to get 
similar bitrates for mpeg encoding, no matter what you're using.

Thanks.  :)  I try to keep my code as readable as possible.  I've also 
tried to optimize the transcode calls as best as I can.


PS. fixing the subject again, so this actually gets file correctly.
