Ok, installed Gamma.. yay me.. Now, like 6 of my Wii backup discs don't work... I'm not talking about non-compatibility... I'm saying the DISC'S don't work... I put them in and I get DVD Read Errors... Alone in the Dark Manhunt 2 Super Mario Galaxy Pokemon Battle Revolution Boom Blox Final Fantasy Fables Chocobo's Dungeon All were playing fine under beta YESTERDAY... then Gamma, and poof! Discs give error... Yes, I've checked them.. no scratches, no smudges... all good... WTF! Anyone else have this issue?
