VDPAU not working on Quadro card

[ApeironTsuka]

Can't find any info on this particular error. According to everywhere I've looked, the G86M core supports VDPAU type A and specifically so does the Quadro NVS 130M card it's in.

Output from vdpauinfo:

VDPAU capture: Enabled
vdp_imp_device_create_x11(0x1f77010, 0, -, -)
VDPAU nvidia: Version: NVIDIA VDPAU Driver Shared Library  280.13  Wed Jul 27 17:15:20 PDT 2011

I've tried 275.21, 280.13 and 285.07 with the same results.

Is there a list of common errors and their causes anywhere?
