ADV7511 HDCP Settings

I am attempting to use the ADV7511 to encrypt the video.    Per section 4.7.1 of the ADV7511 Programming Guide, register to 0xAF bits 7 and 4 need to set to inform the ADV7511 the video should be encrypted and the ADV7511 takes control from there .   I have done this but read back 0x20 from 0xB8 (A/V not encrypted, Read HDCP keys correctly) .  Register 0xc8 is reading 0x03 (Intializing HDCP).  So what should I be doing?  What should I be checking / what am I doing incorrectly?   My sink device is HDCP compliant.  I am using our target hardware.  ADV7511 eval board scripts do not contain any HDCP settings far as I can tell.
