Hi, John, It does help. I'd been having this problem for quite some time now (render to a mov using uncompressed codecs both for audio and video) then unsuccessfully using mencoder for compression with the same errors you reported. I'd never had the care to look for an answer because I'd then use some workaround to make it work. Knowing this about AVIs is actually quite releasing. I'll test when I get home, but thanks for the hint!

Solved.
