Is this problem reproducible with 
ffmpeg -i input.mp4 -qscale 2 -r 25 output.wmv
?

If yes, please provide complete, uncut console output and / or a sample.

PS: iirc (MEncoder is not actively maintained for several years), -mc 0 
instructs mencoder not to do any A/V sync correction, probably explaining 
your problem.
