you will need a tuner than can take a CableCARD (something like the HDHomerun Prime) but before you do that, make sure you cable provider does not encrypt the channels because if so, there is nothing that can be done. Here in the Seattle area, Comcast only encrypts HBO etc.

I second the HDHomerun Prime with cable card. It works great. I get charged 5/month for the card. Much cheaper and more flexible than a cable box.
