I've got a movie that is nearly ready to put on DVD, but with one problem. The video will be about 2 hours long, and iDVD seems to only allow up to 1.5 hours of video per DVD. All my DVDs say they can hold 2 hours worth of video, so what is the problem here? Is there a way to burn a 2 hour movie onto one DVD with iDVD? Or is there another, preferably free, program I can use instead?
