I stripped down the lavc options to where it does not make any 
difference. I had vrc_buf_size in it, but that did not have any notable 
effect to me, so I throw it out to let mencoder use some kind of 
default. I also tried vrc_eq=1, but that does not seem to affect 
anything either, probably because I don't understand this option :o) 
Hm, maybe I need a combination of vrc_eq and vqcomp?

If this helps someone, it's a three day old CVS checkout.
