A couple of weeks ago I had to upgrade my 3 lnb oval dish to the 5 lnb monster dish to recieve my HD locals. I had Directv do this. Since then I have these "phantom" lines scrolling on my screen(all channels), and poor HD quality. My SAT A signal is around 68. I do not have this problem with my other component inputs (dvd etc.) I have tried switching them, but still have the same problem. (not my TV) I have the Directv H20 reciever. Any help will be appreciated.....thanks
