Having your receiver sitting on glass is probably causing a lot more heat than you need, also any type of glass reflection around your DVR can make it malfunction, especially if you use the remote control, and the best investment anyone can make is a UPS battery back up.
I have a Mitsubishi 57" HD TV, and when we get power surges my TV stays on, I can run my TV up 10 minutes after the power goes off, this gives me time to turn it off properly.
