As has been mentioned before, the addition of a simple UPS can eliminate many of these types of problems. Sure, it won't keep your equipment going for more than an hour or two but it can save the grief of 'lost recordings' due to intermittent power outages. The bigger and better the UPS you buy, the longer it will be able to keep your PVR alive. Even the cheapest ($50 or so) UPS can make a big difference. I started out that way and liked it so much I moved up to 2 mid level units so I can still watch tv while the lights are out.
