Query: to control sound system for my TV

I bought this to control my older Yamaha home theatre sound system for my TV entertainment center...that I needed to control with my TiVo remote...so that one button on one remote did it all (the Yamaha has a button for on and a different button for off). This worked almost perfectly, and after I adjusted the sensitivity a quarter turn...if works seamlessly. My TV is rear projection, so when the bulb-cooling fan finally shuts down...so does the sound system. However with the TV off, you cannot turn the sound system on (if I want to listen to CD, radio etc.). Hmmm...maybe I can use a 3-way tap and turn on a small load to trick the strip to turn on the Yamaha. Anyways, that probably won't matter given how you will likely use the device, it works as advertised and works well.
