I found enough info in some threads that apparently a 6.4 IF/UHF Pro Remote WILL control a 722k. However I'm wanting it to control TV1 and when I try to change the address it changes the address for TV2. FYI, the 722k is currently setup for an IR remote on TV1 -- I want TV1 to be controlled via UHF, with the aforementioned 6.4 Pro Remote. Thanks in advance for your replies.
