Your sample is encoded with WMV3 Simple Profile and VC-1 standard
says maximum picture size for SP is 320x240, your file has a bit
greater dimensions. When I hack extradata to treat file as Main Profile
reference decoder does decode it but also not without glitches.
I'll see what can be done and what's wrong with motion compensation.
