Now I am more confused.
All the CAV and A/V gear is in a closet in the HT room.
If I use the 858 to pass IR through an UNO back to the CAV, wont the 858 suffer the same issue as the UNO, that you can only IR to all devices when the UNO is on, otherwise you can only control the last selected device.
If i send all the IR emitters from the ACC IR out on the CAV through the 857 block and then out to the A/V gear, will the UNO keypads be able to ID sources 1 through 6?
Also, a very interesting point on 2 DTV boxes. i hadnt thoughout about that. i do plan on adding a 2nd DTV box in the future. My head hurts and its only 9am.
Maybe i should re-state my goal to solicit the best solution. I do not want my HT room to be a CAV zone, yet I want all my A/V gear connected to the CAV. In the HT room i have a closet that is behind the couches, not near the TV. I plan to hang a plasma on the wall and want to hide all the wires, etc. I plan to use a universal remote to control the TV, DVD, (2) DirecTV DVRs, etc. I would like to be able to pass the IR signal from the universal remote back to the A/V gear that is connected to the CAV, with the 6 IR emitters connected to the A/V gear from the CAV IR outputs. What is the best way to accomplish this and still have maximum functionality from the CAV.
