Mark,

Albert- I use a Sony Rm-VL610 universal learning remote to control my system. You can program it so that the volume functions control an amp/receiver etc. But the channel buttons control your tv or cable box. It's only $30 and so far it has proven to be a pretty good one remote solution for my system.

The AT&T receiver is not line of site, requires RF (radio frequency) remote to operate. The Sony remote you mention may not operate the AT&T box unless line of site and probably does not operate as IR and RF.

I found a RF remote that fits inside a regular remote (like the AT&T RF) and uses radio to generate a sub signal to control a IR (infrared) sensitive device.

In theory you could pair the AT&T RF with aftermarket extender that uses RF+IR.

The AT&T RF would control U-verse box, AT&T remote (IR) controls the Panasonic, and the on board RF to IR converter would send commands to the (yet undisclosed) receiver.

Everything from one remote, (maybe :^).

The Panny also has a TOSLINK output.

I know, and how I wish the TOSLINK output had variable output volume, at the same rate as the TV onboard speakers. Man would that make this simple.

That would make too much sense. :-)
Perhaps a DAC w/ remote volume control would do the trick?

Here's the gadget.

The battery replacement device goes into AT&T remote. When you use AT&T to transmit RF to U-verse box it works as normal.

When you use the AT&T to transmit IR commands to Panasonic, it works in place of the stock TV controller. (These commands are mute, vol up, vol down and on / off.)

When you turn volume up and down for TV, the IR controls TV (already stated) but the battery replacement device also sends RF signal to the extender box that flashes IR to the receiver sensor that will power existing in wall speakers.

In theory a totally seamless operation using same buttons as the other two remote in other rooms. She has nothing new to learn or change habit about. All three AT&T remotes in each room perform the same function with three TV's and enhanced sound in living room. (I hope).

Clever. I hope it works. Please let us know one way or the other.
