Well, looking at another video that plays properly, it also produces 
output that indicates that the video is yuv420p (it happens to be a VC1 
encoded file).

And I'm pretty sure that the ProRes files I have played are the same.

So what about this file could cause the confusion? I see an alignment 
error in the output I posted. Could that cause flipping of bytes that 
scrambles the color? (It does after all appear like u & v are swapped).
