Interesting. Changing from threads=0 to threads=1 made no difference to my test
results. I'm very bad^wlazy and am using the mencoder build from
http://oss.netfarm.it/mplayer-win32.php

This looses two frames off the end (sorry about the line length).

Remove b_pyramid from the above and I only loose one frame.

I'll try to make the time to build my own mencoder and use your patch.
