Hello, I am having a frustrating time with QuickTime. I'm doing the Modest Mouse video competition, and none of the videos that I need to download will work. I have sucessfully downloaded them (per the provided instructions), but when I try to view them in QuickTime, the audio comes out perfect, but the video is completly white. I checked the format, and the video is in Apple Intermediate Codec. Do I need a special QuickTime plugin to view this?
