Well, most importantly, you should be 1-3 meters away from the TV when playing. Secondly, make sure your sensor bar is in the correct place, and you might be able to fix it by moving it further back,or forward, but try different spots for it. Unless I'm mistaken, there's a section for calibrating the pointer, but you probably tried that already... Make sure you have it set on widescreen if you have a widscreen TV, and standard if you have a standard TV. I dunno if I'm of any help, but I hope I can be. Well, if you still can't solve it, try contacting Nintendo's help service. They should be able to fix it.
