My Hopper and Joeys were installed yesterday. The installers set up all 3 remotes with the correct TVs assigned. On the Hopper I added my DVD player with no problem. However, when I try to assign myA/V receiver (Pioneer) to AUX, as soon as I hit 'next' after selecting the brand name, it dumps me out to Remote Manager main screen with AUX unassigned. There's no code listing in any of the Hopper documentation to perform a manual add. Anyone figure this out?
