I'm having the same problem with mine. I can get 119 but I can't get 110. I was thinking that I would need a multiswitch where you can hook two cables out of one LNB to solve the problem but then again... Anyone else out there help?
Dish Pro 500 have a built in switch. Make sure your disq setting are right. 119=1 and 110=2. You might need to load a channel list if not already done so.
