I recently purchased Pink Floyd's Pulse DVD and tried to play it in my MBP 15". When I play it, the screen jitters and kind of pixilates. The main menu look fine though. It plays fine in an iBook and on regular DVD players. I have not previously played many DVDs in my MBP, but I tried about 5 or 6 and they all play fine. By troubleshooting, I've come to the conclusion that it's not a faulty DVD. Has anyone experienced something like this? If anyone has the DVD, do you have the same issue? Any help would be appreciated. Thank you.
