I have a 55 inch flat panel RCA 1080i HD Television. I had HD cable at my home and the picture was amazing. Now I'm in college, and there is no HD televsion here. The picture quality on the TV is a low 480i. The picture looks stretched out and is very blurry. I have tried switching the view from widescreen to standard to movie etc....this doesnt work. Is there any trick to get this picture to at least look like a normal non HD picture?
