I'm guessing you're looking an analog only tuner? I have in my basement a Compro PCI card (Videomate PVR/FM) that would drop nicely into his PC. It is fully functional and I pulled it from my system because my cable service has started transitioning to digital channels. The unit works great and does come with its own software for viewing,recording, scheduling (no need for windows media center). It also comes with a remote.
If you're interested, I can provide pictures. I am willing to sell it for like 20-25 bucks.
