I am trying to create a DVD out of a long (1+ hour) iMovie project that I have. When I export, choosing "For iDVD," the Quicktime file that is created has smooth video but the audio drops out and gets off time. Very frustrating. I have a 933 G4 that has 256 RAM, could it be a memory problem? Any ideas around the possible cause or possible solutions would be GREATLY appreciated. Thanks.
