I installed the kit in my slimline (3 piece kit with SM 3.3), and I had no problem running my "original" games, but when I try to run my "back-ups"... they either do not load or "freeze-up". I never had a problem with my old PS2 (version 9). I have tried both leaving the lid up and being closed. All my games are burned through Nero 6.6 and I use Sony DVD-R. Can some one tell me their steps they use to play the games... to see if my media is going BAD, or what I can do to play back-ups???
