Joe,
Your best bet is a cable box feeding into a video capture card, not a tuner. To feed a tuner, the cable box has to generate an HD RF signal. You will not be able to decode the digital cable signal with a tuner card. (TW may still provide some analog channels, but I think they've gone all digital.)
There are some tuners that can use a decoding card supplied by the cable or satellite provider, however I have not heard of any of the local providers offering this service. This is what you would use with a TiVi branded DVR.
