Use Tivo without Tivo service subscription?

I'm looking to buy a second HDTV but don't want to rent the cable company's cable box. I was wondering if it would be possible to buy a Tivo box to use with a CableCARD but without a Tivo service subscription just for the HDTV programming from the cable company? This is what I do now using a Samsung SMART Media Player and a CableCARD with my current HDTV, but Samsung doesn't make that item any more :mad:

Thanks for any help!
