Hi, > Btw. can anyone confirm that DivX5.0.x _never_ uses INTER4V? > I was astonished to hear that... I don't know about their 5.0.3 and .4beta, but before that - I confirm - never. That's why they have big problems decoding inter4v+qpel, inter4v+bframes (direct mode), inter4v+qpel+bframes... they just don't need it. Radek
