I just got an hd dvr 622 and they installed a superdish with two dp44 switches because i have 5 recievers. They removed my dish 500 and put the superdish. On non hd channels like CNN and Bloomberg, i am getting poor picture quality on all my tvs. The text is not as crisp as it was with the dish 500 and the old switches. Any ideas or anyone else have the same thing happen?
