I have a Sony B50 and an A4 that used to be in separate rooms, but I'd like to move the both to my theater setup so I can record one show while watching another, do pip, etc.

Anyone come up with any good ways to control two Sony receivers in the same place without them both responding to the same IR codes? Before I built something from scratch, I thought I'd see what anyone might have done.

By the way, I have a Pronto remote, so sending other than normal codes is not a problem. Thanks for any ideas.
