I have a few of Divx files that Quicktime will open and play, but the video is totally messed up (sound is fine after the file was doctored). It will play a frame or two, and then nothing but these weird artifacts- kind of like scrambled cable. I read something about files created with the new Divx on Windows being incompliant with Macs- something about B-Frames? I'm wondering if this is my problem and if there's anything I can do about it. Thanks.
