I realize this is already related to other posts on this forum, but there is also an interesting new twist I want to share. Maybe others know what's going on here and/or how to fix it (or is Apple going to???) Until now, I've had no problems with DVD Player, unlike others. I'm running Leopard on a fast G4 tower, 2.0 GHz. I'm in the US, so my discs are region 1. Until yesterday, when a concert disc arrived I ordered. Turned out to be region 2. Popped it in and was prompted to change the region, which I did. All the menu stuff ran fine, but when I ran actual content (music videos, concert scenes, etc) I got lots of skipping/stopping/jittering in the video---audio was fine. Got the spinning ball when I tried to do ANYTHING, like raise the volume, stop play, etc. ALL commands slowed to a crawl. Very annoying. Then the kernel panics began. Ugh! Used Mac the Ripper to put the disc on the HD. It did make a fine "universal" region disc, but everything played just as before. Finally changed the region on the player back to region 1 and VIOLA! No problems! My region 1 discs play fine, as they always did. So what's going on here? Something with DVD Player? A bad region 2 disc (unfortunately I have no uni-player to try it on). Anybody encounter this???
