I have to add, that my solution only work, when a OpenGL-Video is running. So make sure you are using it in VLC, Mplayer or whatever. I am using SMPlayer with "gl (fast)"-Output and Direct Rendering. As Media Center (and my primary interface for video) XBMC with "VDPAU"-Output and VSync. Still no tearing!
