I'm running osx 10.3.9 on my ibook g4. I don't have a super drive. so i bought a LaCie DDV+RW 16x8x16 double layer external drive instead. For some reason i can't use the burn function in iDVD? Its never highlighted. So i downloaded a differnent software called 'handbrake; do the same thing and i've managed to my movie to the disk but the audio is out of sync with the film. Any ideas what i'm doing wrong? As the movie plays fine on my laptop before i burn it.
