[MPlayer-cygwin] mencoder on windows

[Nigel Magnay]

Hello

I have a hauppauge mediaMVP, so I need on occasion to transcode to
mpeg2 in order to view archived divx files.

I'd been using something akin to 

mencoder -o out.mpeg -of mpeg -ovc lavc -lavcopts vcodec=mpeg2video
-vop expand=720:480,scale=720:400 -oac lavc orig.avi

on Linux. However I can't seem to get it to work on the windows
release; it never outputs any video.

Is it some kind of codec issue?
