You will need a TV out from your Video card to send Video to your VCR's Video In and a lead from your Sound cards LineOut or SpeakerOut to your VCR's Audio in, set VCR to Channel AV and start recording.
If you have a DVD Player (not a PC one) that can play the VCD's, then just hook up Video & Audio out of the DVD player to the VCR's Video & Audio In plugs, set VCR to Channel AV and start recording.
