I just updated to OS X Lion and now all my videos on iPhoto will not play in QuickTime Player 10.1. Is this because I need to update my iPhoto to '11? I checked for updates and it says everything is the newest version.
The error message says that either my videos are damaged or the videos are not compatible with my version of QuickTime. Again everything is updated. The version of iPhoto I have is '09. I'm not sure what to do. I have not backed up any of my photos or videos. They do play in iMovie though. If you have a suggestion to try I'm all ears. Thanks for any and all help you can give.🙂
