I'm kinda getting the hump with my Wii not recognising the disc.
I sent it in to Nintendo when Brawl came out cos it wouldn't read the disc and now MPT is doing the same thing. Once it's running it's fine - played for most of yesterday in fact, but to get to that point I have to put the disc in about 30 times before it finally reads. Everything else (barring Brawl) runs straight away, even GC games. It's just Brawl and MPT.
I found PLAY.com have the Official Wii Cleaning kit, and it's only about £6, so I've ordered one of those. It's out of stock at the mo, but I hope when it does finally get to me it'll fix these damn problems.
Spending 20-30mins repeatedly inserting the disc kinda puts a damper on things.
