I have a dual 722 receiver with the sling adapter installed and wireless USB stick. Our second TV is way back in the bedroom at the other side of the house and the remote will not reach the receiver. I want to know if there are any secrets to extend the remote control's range. Secondly, I'd like to use my iPad to control TV 2 using the Dish Network APP, but for some reason, i can only watch TV on the iPad, or control TV 1. Am I missing something?
