When I burn my DVD from Final Cut Express/iDVD, the movie flickers in several areas. I played the DVD on two different players and got the same problem in the same areas. It has happened on two different burns on different days.
Any ideas? It somewhat seems to follow the heavy beat of the music, but not in all areas.
Does it flicker in Quicktime Player after export from FCE? If not, it sounds like a problem with iDVD or your DVD burner. If it plays fine in FCE and after export, perhaps the iDVD forum would be a good place to try.
