Hello, I have a similar problem with the vdpau package. My system informations are the same as Remi's but I'm totally missing the symlink. Adding the link as Remi proposed didn't work for me as applications are expecting libvdpau in /usr/lib/vdpau/libvdpau_nvidia.so.1
Adding this symlink solves my problems using vdpau in mplayer based video players.
