No, CCC isnt a TV tuner. It is an ATi program that goes with their drivers. It stands for Catalyst Control Center. It lets you change 3D settings and overclock the card. Catalyst is a brand of driver, not a company.
To the OP- just re-install the whole driver package, including CCC. Remember to totally clean the drivers using a specialist driver cleaning program (just look in Guru3D and there are some really good free ones) when you uninstall them. That generally fixes problems like these. Also, dont use the disk that came with the card to install drivers. Always get the fresh ones (7.11, soon to be 7.12) off the ATi website.
