I recently had D* installed and coming from Comcast I was expecting better HD picture quality. What I've seen is that it appears that my HD picture is not quite as good as my Comcast picture. It's good, but I guess I was expecting more. Same TV and same TV settings. If I want the best HD picture quality and I'm not concerned with how long it takes for me to change channels, would I be better off with setting Native to "On"? Any thoughts or suggestions would be greatly appreciated.
