Tried it in QuickTime and it murdered it, and RealPlayer at first wouldn't work at all, then it just kept defaulting to WMP.
I found the videos worked OK in WMP. You sounded like you were talking on a badly tuned-in AM radio station and the picture wasn't great, but it was watchable for now. Hope it can be made better though.
Top videos, by the way. They were very interesting to watch. It really brought the project alive!
