Ok, I have seen this around the internet but no solution. I have the latest version of QT installed and even if I change the extension on the file it won't help. Any new info on this problem?
Here are the screenshots of QT and iTunes. Also, I ran the videospec program [very neat by the way, thanks] and see that my problem must be that the video format is DV and I guess I can conclude that iTunes won't play native DV files...correct?
