I've heard other people having this problem too. Sometimes, maybe 1 in 7 times that I go to the disc channel, I click on it and it shows a screen of black for a while. The thing is, it's not frozen; all you have to do is tap it lightly and it works fine. Another version of this is when it works, but only after 30 seconds of black.
Again, this isn't something HORRIBLE that will make me call nintendo, but it's just sort of annoying.
Who's had this problem? What can you do to fix it?
