You used video and audio out cables (usually red, white and yellow, yellow is video) from the VHS, and they go into the DVD burner. You then set the input on the DVD Burner to AV1 or AV2 or whatever input slots you use. Maybe SCART connections if it’s a European player.
The last jobbie I used, which used VideoGlide capture, went from the VHS straight into a USB port on the computer.
If you have a FireWire port (on the camera or computer), there are other (generally better but more expensive) options too.
I have an old Canopus box that takes video cables in and feeds FireWire to the computer. I don’t actually have any FireWire ports on the computer, but a converter to Thunderbolt works.
