I'm trying to get S-video working on my PAL Nintendo 64. So far, I've tried three different S-video cables:
1) Had scrolling diagonal lines across the picture, like this:
2) Had a perfectly clean picture, but was an NTSC cable, and the image was too bright
3) Those scrolling diagonal lines again!
In both cases of the scrolling diagonal lines, the seller said they didn't experience the problem I was having. I'm pretty sure it's a shielding issue, as the second cables were really thick, and I'm assuming, well-shielded. I'm not sure if my entertainment centre is to blame, as I also get noise on the audio of my SNES's SCART connection when I run the audio via my AV receiver (and in this case, the audio is fine until the TV displays a bright image), but then again, I don't have noise issues with any of my other consoles.
What should I do? Is there a problem with my entertainment centre setup (the power board I'm using? I dunno.)? Is there a way I can fix my current S-video cables? Are the there other PAL s-video cables that would solve my problem?
