How to apply HDCP in Protected Media Path (PMP).

Hello, I’m try that apply HDCP in PMP (Protected Media Path).
I had set the HDCP, and given SRM data that required.
But, i had get a error that was “ERROR_GRAPHICS_OPM_DRIVER_INTERNAL_ERROR”.
That error’s mean that srm data was invalid? Or other value was invalid?
Please tell me about that error.
