I have been working several hours on an imovie project and when I try to share the file with the idvd program, it crushes. If I run idvd first and try to drag and drop the file, I get the message "This is not a movie file". It is strange because I have made several dvds this way and it is the first time I cannot get a solution. Even though the imovie file plays perfectly with the imovie app, it cannot be recognized from idvd. I have exported the file as a full quality quicktime movie and have burned it on a dvd without menus and the quality is not good enough. I have also tried to work on a new mac book pro with the latest software and it doesn't even recognize the file as an imovie project. I can only open the contents of the file. Any suggestions? My software version is mac OSX 10.4.11. Perian, flip for mac, mpeg stream clip are also installed on my hd. Thank you in advance.
