Ive been having problems with my Tivo the last few days the picture on UK Gold has been terrible i know its not a good channel picture quality wise but was watching football Arsenal v Bolton on SS2 HD, & the picture was breaking up on that channel to, i changed my settings in digital output from 1080i to 720P didn't seem to make much difference

cant be my TV because its only 3month's old, is there any way i can check if its signal levels.are out.
