    I recorded a movie with isight-a very long one at that-around 3 hours. When I try to play back I receive error message "The movie is not in a format that QuickTime Player understands."

    How to play? I have Quicktime Player 10 running from Snow Leopard.

    Inside the folder for the event in imovie it shows the movie file but with a zero kb size. Also has an imovie cache folder.

    If the file created turned out zero kb I would say it's the opposite to being a very large mov file... Sounds like something went wrong at some point. Try searching your HD for large files and see if you can find if it's still around somewhere.
