It's like the title says. I just got a new, premade machine with Windows 7 64-bit, and VLC, which played the same DVD fine on my old XP box, won't run it now. Oddly, after running the DVD in PowerCinema, which works, it'll play in VLC... with some severe distortion and lag. The drive is called "ATAPI DVD A DH16AASH" in the Device Manager, and the region is set properly to 1 (US). The following is what happens when it won't play at all. Any ideas on how to make it work would be appreciated!
