I've seen the same thing when encoding multiple-passes with B-frames
enabled.  Funny that you have a hard time reproducing it, when I'm
having the problem with every video I try, even with no cropping,
scaling, deinterlacing, etc. Bugs in mencoder seem to search me out...

Looks like michael is the culprit.

Attached is a patch against current CVS based on the changes you
pointed-out. It just reverts whatever it was that Michael was doing
there... It applies and compiles, and I've successfully tested it on one
video.
