Odd issue with 922 Channels not mapping down

[drock85]

Have an odd issue that's been going on for the past week for some reason all my hd channels on 77 and 72 will not map down to the lower numbers. The 61.5 satellite seems to be fine. I have a VIP 922 receiver and Eastern Arc Dish. I've tried running check switch, restarting the box by pushing the button on the front. Even unplugged it for an hour or so. Nothing is working. Anybody have any ideas?
