Hi, I've now got 3 s-video leads for my gamecube and none of them work. I want to hook it up via my AV amp for convenience and the composite looks crap! It is a UK machine and all my leads were bought in UK stores (not on-line) Is there a menu or something that I'm missing? Or are they being sold as PAL when they are actually only for NTSC machines? Any ideas? TA, Richard.
