I've not heard of a scart cable
I do recall (and have) S-Video camcorder and cables.
Quick Google search
S-Video Cables are used to transmit only video signals over a cable by dividing the video data into a color and brightness signal. They are typically used on older televisions that might not have HDMI to improve picture quality.
so,
1. that is still an analog signal, so does PC have a S-Video input? if not, something else doing analog to digital conversion
2. if S-Video, typically then use RCA cables for audio
