I just moved into my grandfathers house.i have a 722k and dish installed a new dish. My grandfather had a 322 that would occasionally suffer signal failure or loose odd or even channels. I thought it might be the dish but it is now occurring with the new dish and receiver. When the guide error occurs it often causes a crash and reboot. The signal loss error goes away if you hit guide and the program's being recorded are fine. Could the wiring be the problem or the receiver? Any help would be appreciated. I am looking to upgrade soon to an Hopper 3 and want to make sure it goes smoothly.
