Finally got SSMB and I got the dreaded can not read disc error so I just send my Wii back to Nintendo for "cleaning".  They had me ship the game and the system.  I backed up everything I could on SD (what a pain to do that file-by-file) and I had 2000 points on there at all.   I've read they don't really clean anything.  What do they really fix?

Nintendo gave me a new Wii. There was no need to put any data on an SD Card because I knew that some data would not be able to go onto the new Wii that they would give me. I got 100% of my data back. VC games, all save data, miis, friends, pics, Wii Points, EVERYTHING!

The only problem....I couldn't edit my miis! It said that someone else made them! >_>; :-/
