Thanks for the information. unfortunately it doesnt help.
I'm using Matrox G550 (running on twin monitors) and i have latest
drivers.

30 minutes late rit dawned on me. The 550 has a setting to control the
overlays. i changed it fro type i to type II an now it works
correctly.
I had the same problem on my video edinting station. the preview
windows were black. there i had to set it to Type I instead of Type
II.
funny matrox cards.
