Hi, I have a Sony Bravia HD TV- KDL-40XBR5 HDTV I have Comcast cable TV, but am dropping it. I am keeping my Comcast hi speed internet service. I have a Comcast cable card in my TIVO, which I assume will need to be returned to comcast. I've Ordered a Leaf HD antenna and will be connecting my TV to it. I can't afford or justify the cable tv connection. I just don't need it. How do I connect this setup to my tivo?? Thanks for any help!!! My TV is near my comcast modem and is connected to the internet.
