I *think* this has to do with a resolution that is not evenly divisible
by whatever block size you use....
I've run into this with mencoder when I pick a cropsize where res % 16
!= 0 - not always, but so far it's managed to get Sponge Bob (no loss)
and Crouching Tiger, Hidden Dragon...
It seems that some codec or algorigthm somewhere rolls the colors over
the divisor, or something like that. I am pretty incoherent right now
due to a severe cold, and I can't say I understand it even when I can
think straight, but maybe this will help.
