Last night I went to watch this for the first time, and was havaing problems with it. It kept stopping on it's own right after the Polydor left the screen. I had to repeatedly keep hitting play to get it to go to the main menu. A couple times while watching the concert, it stopped on it's own too. it was becoming real aggrevating. My DVD player is an Apex AD-1500, and the DVD is a region 0 NTSC disc. This is the first disc I've had problems with. My Grave of the Fireflies is also a region 0 NTSC disc, and I don't have problems with that one. So what could this be? Incompatibility, bad disc, or what?
