This a video I recorded a week ago, and used it as a Video Quality Test on Speed Demos Archive, Nate said it looks great. What is interesting about S-video is that:
* It looks better than the basic composite cables (Yellow, White and Red)
* It's a very uncommon type of video cable here in the UK, most of the accessories you find in retail stores are SCART, Component and/or HDMI.
* While S-video works on my PAL Dreamcast, it does not work on my PAL Wii system, not only it gives out a black and white picture but there is a huge black line across the screen making it pretty much unwatchable.
