S-VHS cable only carries the video signal, no audio. Connect the audio with a separate cable from your cameras AV out to the AV in on your capture device.
Ulead software came with a purchase of WinTV-PVR-350. This card did not come with necessary items to use the card. I thought S-cable was all that I needed to buy to make it work. After you posted the reply I brought an adapter to connect the RCA cable into the card. Now it works. Thanks.
