I would like to use vdpau with gnome-mplayer on mint13-cinnamon (nvidia proprietary drivers). It works, but each time I load a movie, I have to visit the option panel and close it (wihtout changing anything). Otherwise I only get sound (black or grey image). I tried to replace mplayer2 by mplayer and have the same behaviour. Actually, I use "gl" instead of "vdpau" (in gnome-mplayer options) as a workaround, since I don't want to open the option panel each time (particulary in a web plugin). However, I would prefer to use vdpau since its cpu usage is much lower. Since I know it's working, it should be easy to get rid of this small anooyance, no?
It seems to be a "bug", but I did'nt find it reported elsewhere... I harly believe I'm alone in this situation.
