It's the CDR's. Definately. I also tried taking my Dreamcast out for a spin lately and my backups didn't work. I just reburned the games I wanted to play and it worked without a hitch. I think leaving them there for too long in the heat caused it. Also I didn't put them in a CD wallet. Just left them lying there. Very irresponsible :P
