I am using Backup Launcher 0.3 gamma. I have burnt a few games and they have worked but some don't. I use DVD-Rs. When I try to load CoD: WaW PAL version, everything works but the screen constantly jumps. I can't see a thing. Another game I have problems with is a Zelda: Twilight Princess PAL version. It does the same thing. It loads but once it starts, the screen is moving downwards constantly. I used a DVD+R for Zelda. I'm not sure if it's a bad burn but I've burned my other games the same way and they work. Can someone help me fixed this problem?
