Hello, I dl some .avi files but to my surprise, Quicktime player doesn't read them. I can hear the sound but the screen in the window player is snow white. A visit at Apple site suggests some other players like VCD X. Same thing with this player. I don't know a thing about codecs and things like that. What is there to do to have Quicktime player show them? Here's what the "Info on sequence (french) " window of Quicktime player tells me: "MPEG de couche 3, Stéréo, 24,000 Khz XVID, 512 x 384, Millions". I'r really like to see these sequences. Thanks a lot for your help Germain iMac G5/1.8 mhz/512 ram Tiger 10.4.2 français
