With the new 163.71 WHQL Nvidia drivers, if I activate WMV dxva using the WMV Powertoy, the WMV9 decoder gets accelerated and now both cores read the same low level (8500GT).
However, I get system lockup and instability after a short while and a blue horizontal bar in the MPC window at the bottom (very similar to the grey bar when decoding 1088 versus 1080 mpeg2 material that I recall from ages ago).
Oh well, it's some progress, but a multi-threaded WMV9 decoder would be good: one of the cores is hardly getting used whilst the other is getting dangerously close to very little headroom.
