Are you sure connection 4 S-Video in on the back of your VCR is S-Video in? If it is, then it won't work as you need S-Video out going to S-Video in on your computer. But is your VCR a VHS model or Super VHS model? If it is only VHS then there is no point using S-Video because the improved picture benefits won't be there in the first instance. Is 1 [yellow composite video]
an in or out connection?, it needs to be an out connection to take the composite picture signal out from the back of the VCR to the composite in socket on the computer.
