Hi, all. Ive been watching the Alien Quadrilogy on my MacBook Pro. 1 and 2 played perfectly but Alien3 has frozen 3 times late on in the film. The dvd would stop spinning. The only way I could come out of it was to force - quit. I searched around and there was talk about Seamless Branching problems. I wondered if this was the cause. Does anyone have any info on anything related to macbook pro dvd problems etc?
