Hello, I have almost the same setup as you, but my video-output is flickering when there is a lot of movement in the film.
I have tried mplayer and xine, different kernels 2,4xx & 2,6xx but the same thing happend.
Have you or anybody else the same problems ??.
It looks like hardware video-overlay is only possible on one of the screens, so how do I adjut my XF86Config file to have it on the second monitor. ??
