Has anyone looked into how much power they are using to run Tivo continually? Is it like running a computer continually. I've blown a few fuses in the house. I have more than one Tivo. It never occured to me to consider whether this old house I live in with fuse box can handle my personal computer plus a couple of Tivos. I'm wondering if I should turn one of them off over night, but I bet I will forget to turn it back on in the morning.
