A little while ago I bought a USB video capture device for archiving recordings from my Sky satellite box. The capture device has composite and s-video inputs. Naturally I wanted to use s-video, but I found that the quality over s-video was very poor compared to composite. I assumed there was either a fault with the Sky box or with the capture card.
Recently I got an s-video cable for my Super Nintendo and connected that to the capture device. The s-video signal was again very poor compared to composite, so I thought I had confirmed that the problem was with the capture device.
However, when I then connected the Super Nintendo directly to my Epson EH-TW3200 with the s-video cable, the signal was just as bad as it was through the capture device. So now I'm really confused. I though s-video was supposed to be better quality than composite, but with two different sources (the Sky box and the Super Nintendo) going to two different display devices (the projector and the USB capture device), composite looked better than s-video.
I have attached two pictures. The first one is the Super Nintendo displaying via the composite signal on the USB capture device. The second picture is the same thing but displayed over s-video. As you will see, the composite is significantly better quality.
An advice would be much appreciated.
