This feedback was provided under Windows 7, however action has not been taken to correct this issue for Windows 8 either.

ERROR:

Display driver error – the video playback device does not support playback of protected content.

ISSUE:

Media Center with a CableCard tuner doesn't work at all on DisplayPort, because DisplayPort is not detected as HDCP compliant by Media Center. CableLabs Certifited DisplayPort as HDCP compliant but Media Center still hasn't been updated and it still thinks that it's not compliant.

REQUEST:

Requesting Microsoft to produce a patch so that DisplayPort is detected as HDCP compliant by Media Center.

    Just bought a new Dell XPS12 and upgraded to Win 8.1 with WMC. Same issue as above. Dell refuses to address issue as they feel it is a Microsoft driver issue. When is Microsoft going to address the Displayport HDCP compatibility problems????

    Don't count on it as it may never happen. I've since moved from a Cablecard tuner to the Hauppauge HD-PVR which records from the cable box via the component connectors. I can view the material on any device I wish. I was not able to distinguish any loss of video/sound quality.

    There are of course many limitations with this approach, but from a practical standpoint I'm much happier after the switch.

    It's one of those cases where it's so much more difficult to be compliant with their rules that you're better off circumventing the entire thing. Overall a ridiculous situation.

    a new version of the OCUR spesification came out on June 7, 2013. you can see it here

    http://cablelabs.com/wp-content/uploads/specdocs/OC-SP-OCUR-I11-130607.pdf

    page 36 says "HDCP active on digital display outputs (such as DVI, HDMI, and DisplayPort) for live or trick mode play and for playback of recorded content if any similar

    recorded content is HDCP protected." 

    as oposed to the  old version which only said something like "HDCP over DVI or HDMI"

    so how long does it take form a specification change to a patch?

    PLEASE MICROSOFT, FIX THIS.
