Gamecube Disc Read Error, Disc has white marks.

I've had a used Gamecube from Gamestop for about 8 months now, and it's worked fine for the most part. I've had Rogue Squadron give me a DRE once; I cleaned the disc and moved some stuff away from the air vents on the side since it seemed to be a little warm and it worked fine.

I just got Metroid Prime from GS today, and after a few minutes it DRE'd. I noticed that once it spun up, the disc made a different sound than usual. I looked at the disc, and there are some weird white marks on the clear plastic next to the hole that where the spindle goes. I can't feel them on any of the surfaces, but they look sort of like heat damage. Any suggestions? This was the version of MP that has the second disc with a MP2 demo on it, so would they just trade the one disc and let me keep the special disc/case?

if it still reads some games then its the disc or you need to clean your laser

my gcn never ever did that

TC, it appears that your copy of MP1 needs to be repaired, as those white marks are actually deep scratches, which are causing the GameCube to send out the DREs.
