Nark,
No, the current U-verse box I have is IR, the RF is an add on. I did not think about repeater for IR since I had such good success with DIrectTV RF all those years.
I think what you're saying is maybe use repeater IR and let it control the U-verse and the integrated (TBD) that run in wall speakers.
Is it possible for the AT&T remote to do volume and mute via IR on a audio receiver or can you buy alternate code transponders so everything works together?
I hope all this helps some other Audiogon member, it's a mess trying to tie this together.
