The HD-capable TiVos (the S3 and the TiVo HD) cannot use a cable box to tune channels. They use CableCards and OTA antennas.
That card you see sticking out of the cable box is not a cablecard. It's some sort of access card. I think the different cable companies do different things. For me, they slid that plastic access card into a metal sleeve and then slid that into the TiVo S3. I believe there are some CCs out there that don't use the plastic access card and just have the data programmed into them.
