Comment (by babgvant):


 The source stream doesn't seem to matter. Every source I've tried has
 reproduced this issue. I can try to find/create a smaller file (the ones I
 have been using are very large) if you want.

 I have tested on two PCs, both running Windows (10/8.1) with the latest
 drivers from Intel for each (i7-4770k/i7-3770s). Native QS
 decode/encode/VPP works in both systems using another MSDK enabled
