Cammo's suggestion is also my recommendation. In addition to Xantech's offerings, you might investigate the IR extender kits offered by (among others)
Crutchfield. You shouldn't have to spend more than a couple of hundred dollars.
You place a tiny adhesive-backed IR receiver module near the front of you TV (where you would "logically" point your remote). A thin wire relays the signal from there to the a hub in your stereo cabinet. The hub then relays it through IR repeaters positioned inside the cabinet where your components can "see" them, and you're there! Good luck, and let us know how you finally set your system up. -Bruce
