Hmm.. perhaps TVs have a special feature which is to prevent flicker at 50-60hz, perhaps it's scan doubling? I'm able to tune out most of the flicker on my a1200 and lcd flatscreen, but it's still there and fairly obvious in hires lace.
My "Magic VGA" scan doubler will arrive tomorrow. I'll do the a1200 -> s-video hack over the weekend and post the results.
Have you connected your CDTV to a vga box using s-video? If so, how are the results? Any flicker? Color bleeding?
Thanks
