So I finally moved to the new tivo's. After having three S2's, and with Charter in my area going totally digital, I decided to get a Roamio. I'm sure I will have some questions, and will be looking around here for answers, but I have a question about the CC. Not ever needing one, I thought it was just a card. I went to the cable co to pick one up. They gave it to me, plus a little box, about the size of a small cable modem. I asked what it was for and the agent had zero idea. After going thru tivo install I inserted the CC. Couldn't get it to work. I called Charter and they went thru some stuff. During the call I asked them about this little box and they had no idea either. Since we never could get the tivo to work with the CC, I decided to try and plug the box in. So, I put it between the cable and the tivo. After quite a while the tivo started to get channels. Is this box normal? I didn't think anything else was needed with a CC, but I guess I was wrong.
