Well I've had my Cox DVR for over a week now. Works great. I agree the user interface is not as cool as TivoHD, but at least it works. And I also have On Demand which is pretty cool. And I am also not paying $12.95 a month for something that does not work. And the channels also change quicker. Finally some peace of mind. Oh, and Cox did credit my account for the 6 days Tivo was getting the firmware update!
