Hi, I'm totally new to TIVO. I've looked online and can't seem to find a straight answer to my question. I hope someone can help. I'm very tech-savvy, so whatever I need to do to make this work, I can figure out. I just bought a TCD649080 (Series 2 80hr recording) Tivo off Ebay. My roommates and I want to just use OTA to watch shows - we don't want to pay for cable. It's the whole reason we bought the Tivo - to kick cable. But I can't seem to figure out if the TCD649080 can work or not. Any help on how to make it work is greatly appreciated. I have a Sony Bravia HDTV and no external antenna as of now. Thanks!!
