I am using discs R- and i downloaded goldeneye wii yesterday. Everything went fine. burned a copy for my friend and he tried it and we had a few disc problems. Well today my disc is having problems as well. It was burned at 4x so I burned another at 2x (although I think it said it had a write in error so It may have burned it at 8x lol I am not sure now...) I have a 4.2 U I have neo R8 beta 15 IOS 249 and REV 17 in case you were wondering. I am just wondering why yesterday I had little no no disc errors.
