I have a 8642HD pvr supplying signal to a HDprojector.
I have added a 4642 HD box in the same room to supply signal to a 60" plasma. Beside the big screen.
The supplied remote changes both boxes when it is used. I remember years ago before HD having 2 boxes together and there was instruction in the owners manual to change the remote and box to a different control channel so each remote would only control it's own box and not both. So, one remote on channel A and the other on channel B.
I can not find any instruction on how to do this. Is there a fix or has technology moved backwards?
