Trying to get the best video quality with my consoles (and other problems)

[markusman64ds]

It seems to me large amounts of white or certain other colors are a problem. On my CRT with your above linked converter I can get Sega Genesis screen rolling over component in specific parts of games, as if they output too strong of signal. Consistent results (like file select screen) make Sonic 3 a very useful test subject.

Oh, that's what screen rolling is. I had no idea. So is it that the TV can't handle the signal?

And do SCART cables output audio, or do I have to get a specific cable with audio cables?

EDIT: You own the converter, so can you confirm if it uses European or Japanese SCART?
