Okay, this is only a guess but...
When I wanted to transfer video from a camcorder to my computer I had to capture the video through a firewire port with my
NLE program. In my case, that was
Adobe Premiere Pro. I have to play the video on the camcorder in VTR mode and record it, in real-time, on my computer with Premiere.
I'm guessing you will need a video capture program to detect your videocard as your local VTR device and record its input. I'm sure any NLE can act as such a program (like Premiere did). A good way to test this theory might be to try
VirtualDub. It might be able to capture video in the manner that I mentioned (go to menu: File/Capture AVI...) and, best of all, it's free (open source, even!)...
Good luck...
