Yeah, I don't need a tuner. I'm strictly capturing video output from the DVR into the capture device.
I don't have a PCMCIA thingy, but instead I have this ExpressCard 34 thing. Never even realized that. I thought it was just a holder for the little remote that came with the laptop.
The USB capture device I'm using at the moment is some Diamond One-Touch video capture device that I ordered dirt cheap. It comes with some One-Touch grabber software and a VHS converter application.
