I have a 622 in my bedroom but the primary TV is the plasma in the living room. The installer said the #1 remote must have clear view of the receiver in order to work. In other words it won’t work through the walls. Since I have my plasma on the wall with no AV rack, I have no place for the 622 in the living room. I have been using the 921 for two years this way. Any help? Surely the has to be a way around this.
