Plain vanilla: the simple way to get the signal to the other room, if you just plain want it there somehow, is to take the channel 3 output of the tivo and run a wire to the second room.

Xantech has a thing called the Xtra Link that can receive an ir signal in the other room, stuff it into the RG-6 you are using for channel 3, and then reradiate IR in the other room to control the tivo.


For better quality, run the tivo audio/video output through a DA (distribution amp), then feed one of those outputs where the tivo output goes now and another to the a/v inputs of a tv in the second room.

Also, then, you would run a CAT5 and use Xantech's 281 or 490 to pick up the signal, get a power supply and distribution block, and a 282 or 283 IR LED to reradiate the control signal in the main room.
