I'm trying to capture some video for some projects of mine, but I noticed that said videos have a really weird checkerboard pattern.



It's especially noticeable on my Gamecube, hard to see on my Dreamcast, and virtually unnoticeable on my PS2 (I only get it with very specific games). Both my GC and my DC are using third party cables, but I'm using the official S-Video cable on my PS2.

I was wondering if this was being caused by bad S-Video cables, or if there's something else going on. I think I'm using Pelican cables... should I be using another brand?
