Just bought myself a nice 50" HDTV. I'm dying for another Tivo. This SA 8300 DVR is driving me insane. I have Knology in St. Petersburg, FL. I called them up to ask if they could hook me up with a couple of CableCards for the TivoHD that I plan to buy in the next couple of days, if everything turns out OK. The person on the line told me that they had not rolled out HD service through CableCards. They told me that I could get HD service through their STB, or "SD CableCards", but not "HD CableCards" Is there even such a thing? I was under the assumption that DTV broadcasts are broadcast in both and that there is no designaiton for HD or SD CableCards. Can someone set me straight? I did call them on a Saturday, so I'm sure I didn't reach the shining stars of the cable company (ha!), and I plan to call back tomorrow.
