Anyone know, can I run the output of a Direct ty receiver into the antenna/CATV input of a 622? I recently reconnected to D* to get my lost distant networks and I would like to use the 622's features and the distribution system I've set up. So far, when I go to System Setup and Local Channels on the menu I don't find a signal on Ch. 4 where the D* receiver is sending. Am I doing something wrong or is this not possible? Dish tech help really doesn't get this at all.
