VLC could render with VDPAU on your card, but it would require software 
conversion from I420 to NV12. You are better off using XVideo than VDPAU then.
The only benefit of VDPAU would be finely scaled OSD, at the expense of 
performance in this case.

In fact, it would work just fine like normal if you had not needlessly forced 
VDPAU as video output in your preferences. If you want to accelerate video 
*decoding*, there is dedicated option for that.
