Remote Problems Resolved
A dish tech determined the cause of my remote problems. The TV is somehow interfering with the reception of the IR on TV1. If you turn off the TV, the remote works propertly. When the TV is on, it works intermittently. The TV is a Vizio 47" LCD 1080P 120hz. Dish replaced the TV1 IR remote with a 2nd UHF remote set to a different address from TV2. All works well now. The tech said they have seen multiple reports of this problem with the 722K.
