Wii problems.. anyone else?

My two older games DBZ TK2 and wii sports suddenly freeze every time i go ingame now. Very few scratches too.

I bought SMG, and when i press the "home" middle button of the controller. It freezes my wii. If i don't touch it, no problem at all.

Both things, i have to unplug the wii to fix it. No real big deal with smg, since the pause button is actually the button right next to the home button. Making the home button useless anyways. But still... this freezings annoy me.

That isnt normal... you should call Nintendo.

This has began happening to me also. Sometimes I will start a game and it will freeze with a black screen and sometimes when I go on the Disc Channel, the disc won't even load and it has an error messege. No biggy, I just unplug it.
