I moved and had new cable cards installed. Everything was fine, to include loading program information. However when I decided to run Guided Set Up, it gets stuck the second time at "Preparing". I pulled the plug after an hour, but after powering up I am returned to Guided Set Up and can't get out without going through the process.... where again I hang. I called Tivo and they tell me there must be something wrong with the box, you can't get out of Guided Set-Up unless it finishes, so I need to do an exchange. WFT - the box was working fine until I decided to run Guided Set-up. I don't really want to exchange as I added a 1TB hard drive years ago. Any suggestions?
