My new DVD Player came with a red/white cable and a yellow cable, all looked pretty crappy quality.

I used a toslink digital output cable for my audio and had a spare gold plated red/white cable laying around so I decided to use half of that to connect my dvd's video to my receiver (better than the crappy yellow one right? well....wrong)

The "better" gold plated cable gave diagonal wavy lines, suddle, but they were there [I notice the small stuff], however the yellow cable didn't give me this problem.

What's the deal with that? Are some of those cables that look EXACTLY the same only meant to carry audio?
