CUVID not working with SLI in windows 10 #545

Describe the issue you're having:
Can't use CUVID as a decoder option with SLI enabled in Windows 10 (Other 
options work).
Just get a black screen with I try to play any video files.
Worked in Windows 8.1 with the same hardware and SLI (only change is Windows 10 
and the Windows 10 nvidia drivers (355.60)).
It works in windows 10 if I disable SLI.

How can the issue be reproduced? Sample File?
Probably need a SLI setup (I have 2xGTX970), CUVID enabled and Windows 10.
Might need MPC-HC, haven't tested without it.
Don't need madVR, tried to use system default, but same issue.

What version of the product are you using? In which Player?
MPC-HC 1.7.9 x86, LAV 0.65, Windows 10, Driver version 355.60.

I can confirm this behavior. I'm running two GTX 960s. Selecting CUVID in LAV video decoder prevents videos from playing. Selecting DXVA or disabling SLI prevents this behavior.
