Im having problems running this on my TV. I have a 27" TruFlat RCA TV. It runs fine on 1080i and the lower 480p i think it is. But when running 720p it distorts the image. Enlongating it and multiplying it. So Ill get like 2-3 images across my screen of what I should be looking at. Is there some setting im missing? Something I dont understand about using it on that resolution? Can anyone help with this please?
