Paul,
I use a Kworld DVD maker USB 2.0

I have also used a AverMedia PCMCIA capture card, either capture system works fine but I suggest that if you go USB (as I did) mark the USB port you install the camera on and make sure you plug into the same port each session, if I don't do this I've had problems detecting the video correctly.
The Gstar software will create avi files for direct import to registax (although I have had some issues if the avi files are too large).
FYI the G-Star software works with any video capture/webcam camera.
Cheers
Garin
