ADV7441A:HDCP authentication failure

I am using a HDCP key enabled ADV7441A. In my board port B is connected to HDMI input and port A is connected to DVI input. A blue ray player when used as a source, gives a black video, When connected to a test pattern generator capable of doing HDCP compliance testing, i get an error "Could not write An to Rx" in port B and "[ R0(0xAF40) did not match R0’(0x0000)" in port A. I am using internal EDID for both the ports in my board and is being read successfully by all the sources. Why is this HDCP authentication failing ?...can anyone help ?.

 

Thanks,

Mani.
