Query: DO NOT BUY THESE CABLE!

There is con artistry at work here. As soon as I plugged these 25 ft S-Video Cables in I saw crosshatching across the image, additional wavy lines, and a large roll pulse up and down the screen. I tried plugging them into different devices, moving them away from outlets and power chords, using different TV's. The bottom line: these cables don't work. I guess I should have known based on the price but I thought if they were Amazon approved they had to have some value.
