Automan,

The s-video cable uses 4 runs of belden 1506a cable. They do not use the shield for signal return. The cores are the only part connected. They are therefore heavily shielded. If you check around you will find quite a few of the better S-video cables use a similar design. The picture results are stunning although the cable is stiff and bulky. Not what I would call flexible but the results far outweigh this minor negative. The cable was custom made for me so I cant speak to the importance of 75 ohm rating. But then who cares because the picture more than speaks for itself.
