Help! I'm a video newbie and I'm still learning the ropes of final cut. I tried to export a video I made as a .mov file. It plays fine on my laptop mac, but when I burn the file to a dvd and put it in my desktop mac all I see is a white screen. I hear audio but that's it. Am I exporting wrong? Is there a particular way I should export it so it's playable by quicktime on all computers? Thanks!
