i already tried some screenshot-tools - none of them worked...
in the screenshot picture VLC is always black - no video seen..... how can i aquire a screenshot like this one?
You need to disable overlaying in VLC's preferences to be able to make screenshots under Windows. You should find an entry about that in the video-section.
