Ok so I have recently acquired a vip612 replacement for a 522. Unplug the old, hook up the new and now only have 1/2 the channels I had before the swap. Original dish never moved. The dish currently in place is a 500. I know the 612 is a HD receiver but I do not currently subscribe to HD, so it shouldn't matter that it is a 500 dish or does it. Just curious on your thoughts. I'm thinking a 1000.2 dish or am I just waiting money? Thank you for your input.
