I want to make a DVD with iDVD but my .mp4 movie is too large. The notice says that "Your project exceeds the maximum content duration. To burn your DVD, change the encoder setting in the Project Info window." so i changed to encoder setting from "Best performance" to "High quality" but then this screen comes up. http://tinypic.com/r/2mrbeaq/7 Notice how it does not encode and im left with a gray shade? I tried to burn it, but it says "There was an error during the encoding process" Any suggestions? Thanks!
