My 622 was installed on 04/13. Local channels on HD 600+ and other channels using Sat 129 shows low signals causing pixlating and freezing the 622. I called support and reported the problem. They sent a teck out. He said that the dish on my roof could not be adjusted and that the problem was caused by Sat 129 and the 622. Supposedly Dish network is working on fixing the 622 and the satelite and that the problem of low signal would be fixed within a week. Should I believe this story? Does anyone else have the same problem?
