Could I not fit an S-VHS plug to one end of a spare Scart cable I have? My laptop has S-VHS socket and my VHS has Scart socket. Or is there something special in those devices that can be bought that converts the signal in some way?
Unless stated I suspect the 'video' card of the laptop is output only.
Anyhoo, once you crack the wiring/capture capability I hope you've got oodles of RAM & hard rive, video capture and rendering is memory/storage intensive.
