The new feature set D GT520 vdpau decode bit stream processor is capable
of twice the throughput of set C. So 2 full HD streams (real stereo).
The shader performance is similar to GT210; not very good.

BD material is mostly progressive scan so there is little for the
shaders to have to do. 
It would be nice (for BD playback) if the shader programs included frame
creation similar to VA de-interlacing. This is driver software not h/w &
could already exist.

So if you like BD 24p & don't care about VA de-interlaced broadcast then
GT520 is a good buy.

Have only watched one BD in Myth so am not convinced about the 24p
look...
