Hi guys, I seem to be having a problem running backed up games on my PS2. So I burned the game (Persona 4) using ImgBurn at 2.4x speed, and it played very well. I was able to play the game perfectly for the first two days. Then, after a while,the game began to freeze at times. I restarted the game, but Swap Magic would give me the message "Not A Valid PS2 Disc". Occasionally, it would get past that, but the screen would stay blank. I tried burning another copy at 4x speed, but that one didn't boot up at all. I'm using Gigaware DVD-R's, if that matters. And I have a PS2 slim. Any help on this issue is appreciated. I've been frustrated for hours now.
