I have two R-22-100 receivers connected to an SWM8 and have recently installed a Slimline dish. I seem to have good signal across all the satellites on both receivers. On the upstairs receiver, in settings, I have a menu selection to "Hide HD Channels" or "Show All Channels". On the R-22-100 downstairs this selection is grayed out and I cannot change it. Any ideas why this may be?
