I have a V-Stream XPert TV-PVR. Not a name brand, just a cheap one I picked up a few years back at one of those computer show and sales they have (don't know if they have them in your area or not so you maynot know what I am talking about).
As far as I know, it is tuned to the correct port. I have the following choices: S-video, Composite, Antenna, Cable. I assume that the correct choice would be Composite.
