Are Playstation component cables just pass-thru or do they have electronic gubbins in there too?
I made a cable last year for my PS2 which appears to work with RGB but not component. It doesn't work with HD resolutions on my PS3 (my TV says "no sync" and goes into power saving mode)
I'm having no luck finding one locally at the moment, and I don't fancy ordering one just to find it's the same as the one I made and can't return it.
