Yes, DirectFB composite == Windows Composite / S-Video. > even so, the yellow composite plug from the original Matrox adapter > always carries composite signal.

That's how I think it works too. The only thing that keeps bothering me is that I don't know what scart-composite does differently and I don't have the equipment to analyze the signals. On G450/G550 the situation is different though. It uses vsync as the sync signal in scart-rgb mode. -- Ville Syrj�l� [EMAIL PROTECTED] http://www.sci.fi/~syrjala/
