Just purchased it on friday and must say i am amazed by the quality. I see rainbows but don't really care too much about it. I notice it more when i'm tired or i've had a few beers but don't let it bother me too much. What is the best way to connect my basic sky box to it? I've got a component cable going to it but surely i can get a better signal to it than one single cable to the yellow input on the back of the projector.
