I'm considering upgrading to Genie for a number of reasons. One of the things I'm trying to weigh is the cost of running my two boxes now. I'm currently running a HR22-100 and an HR21-700. I've heard horror stories of DVR's using as much power as a refrigerator. I don't know that I believe that, but I don't have any way to test/confirm that. Do any of you know how much power these units are using? I'd assume the C31 uses relatively little power since there is no hard drive, tuner, etc?
