Does anyone have the good instruction sheet, from Tivo's support pages, on how to install CableCards in the Tivo HD that they can post? I remember there being a link in this forum to a tivo.com support page that provided in depth detail on how to install the cards in the Tivo HD. Now I cannot get anywhere on Tivo's support page. Most the time the links time out or are broken. I have no idea what is wrong with their site. But my dad is having Comcast come out tomorrow to install cable and I wanted to print out that instruction sheet out for him. Also, Tivo recommends to run the guide set up BEFORE Comcast comes out to install the CableCards. My dad is in a new house and doesn't even have cable installed yet. Should I run the guide set up telling the Tivo HD that he has Comcast cable without having a cable feed yet? Or does the Tivo have to detect an incoming signal?
