I bought my Wii last week and everything worked fine until last night. It gave me disk errors 3 times while playing Wii Sports, even though the disk looks fine to me, except for a fingerprint or two. This happened twice upon inserting the disk and once in the middle of a tennis match. So do you think I should return it? I was planning on installing a WiiKey tomorrow, but would rather not if I'm going to keep running into this problem. I know from modding my Xbox that if a drive has trouble reading originals, it tends to have even more trouble reading backups, and I do plan on making backups. What should I do: wait and see if it keeps giving me errors, or return it? Has anyone else's Wii given them trouble reading regular game discs?
