hello, my wii just started (a few days ago) to give a disk read error when i try to load mario party 8, i checked it and it had a few scratches that were round from being in the case,minor, so i tried to buff it with a skip dr. and seems to have removed them but i still can't get it to read, it will say what game it is in the channel menue but from thier it gets the error, i also have wii play and wii sports and a few gamecube disks that all play fine, could it be that it cannot read dvd any more? does anyone know if wii play and sport are dvd or cd's? i also just got my wii key and wonder if installing it would be a bad idea of good? i saw i can change dvd read speeds and thought this might help. any input from you guys would be great!
