I am having trouble getting VDPAU to work under my 9600GT running Ubuntu Linux 10.04. The precise error (when running vdpauinfo) is as follows:
VDPAU nvidia: Version: NVIDIA VDPAU Driver Shared Library 195.36.24 Thu Apr 22 19:52:55 PDT 2010
VDPAU nvidia: Error detected 0 6291
VDPAU nvidia: Backtrace:

Error creating VDPAU device: 1

I have tried removing and purging the nvidia-current package from my system to no effect. In addition I have also tried installing the latest version of the libvdpau1 package from the vdpau PPA repository.
OpenGL works fine, no issues there and have no other reasons to suspect the driver is not functioning properly. Bug report attached.
