For around $200+ you can add full house surge protection to your circuit breaker box. My electrician said to buy from an electrical supply store. I've not added one yet, but would like to.

I currently have my home theater stuff hooked up to an APC J15.

There's also a rechargeable light plugged in under the TV that's switched off, but comes on automatically when the power to the house stops, to let me know to shut down the theater. So far, I've not lost power this way since it's been installed.

I know this doesn't address your problem, probably, but at least I get a chance to tell about something in my system.
