Ok got a wii set it up, but on my 50 inch plasma tv when you aim in the middle its fine but as you aim towards the edges the pointer speeds up faster than your hand moves i'm stood about 5 feet from the tv and the sensor bar is on top of the tv. i've tried adjusting the sensitivity but no joy. can anyone shed any light on the situation. the tv does have a black shiny strip around it could this be affecting it. the wii works perfect on the portable.
