Advertisements I saw on another thread about a guy selling his tivo on ebay and the OP there was upset that it looked so clogged up...and that it was being sold like that. Maybe this isn't a happy hour question, but you all are as smart as the geeks on the other tivo areas (the tech ones) and I am comfortable here, so I thought I would ask. I have two dogs and lots of dog hair. I am actually scared to look at the back of my tivo now. I do have some air to blow it out, but how is that done? It's my bad but it's been two years and seems fine. Okay, I have never done it to my computer PC fan either. I have only used the air on the keyboard. And one more question, is there any sort of cover to put on the tivo to save it from dust and dog hair that won't over heat it. I don't have and can't get anytime soon a glass entertainment type dealie.
