Could you please provide more information about this configuration?
What are you referring to “copy-once”?
Would you like to know if your graphics controller is HDCP Compliant?
Could you please attach the result of the Intel® System Support Utility?
To add more information, This CPU also offers DirectX* Video Acceleration (DXVA) support for accelerating video processing.
— Full AVC a.k.a. MPEG-4 Part 10 or h.264/VC1/MPEG2 HW Decode
The Copy-Once flag is implemented in the stream itself, and as long as it is decoded with MPEG-4 Part 10, then it should work.
Hellen, I'm not sure I understand the extra information you provided as I am not sure it is an amswer to my question. You seem to be saying that Copy-Once MPEG-4 Part 10 should work with this processor, so I should not have a problem. However, your answer seems to be general to the processor's paper capabilities, and not specific to versions of Windows and drivers. Since it is well documented on forums such as The Green Button that there are problems for HD4600 graphics processors like mine displaying copy-once MPEG-4 in Windows Media Center from cable TV providers such as Cox Communications under Windows 7 I don't think that helps me much. Could you please research the specific issue of HD4600 graphics and copy-once MPEG-4 from Cox Communications under WMC And Windows 7 and see if you can turn up anything more specific in terms of Intel's status. Thank you for your help.
I can confirm you that playback of h.264 protected video content is supported by Sandy Bridge (2nd gen Core) processors and newer. They are HDCP 1.4 compliant.
I have reviewed customer posts at http://www.thegreenbutton.tv/forums/viewtopic.php?f=5&t=9635 and most users have a configuration that uses HDMI Extenders. If these devices are not HDCP 1.4 complaint then it would be expected for the video stream to fail.
If this is not your case, please fill out our sticky note, include type and brand name of video cable and adapters.
Default level information for reporting Graphics issues
I can confirm this issue does indeed exist. Issue is with Intel's decoding of Copy One (0x02) MPEG4 Encoded streams provided over Cable Card tuners. I have a Intel NUC NUC6i55SYH running Iris 540 graphics and driver version 126.96.36.19901 on Windows 7 SP1 64Bit, and get the video error consistently on protected Live TV streams. Using a much older NV graphics Card. Error is "Display driver error" and then "The video playback device does not support playback of protected content."
I’m just following on this thread to ask you if your issue was resolved or if you still need further assistance. If the problem persists, could you please fill out the information from the link above when you have a chance, attach the Intel® SSU file, the Dxdiag and the report that you can get from the Report for Intel® Graphics Drivers
Answers (N/A if not applicable)
Provide a detailed description of the issue
Live playback of MPEG4 encoded DRM video stream from Cable Card Tuner does not decode on Intel GPU. Black screen w/ audio only. MPEG2 encoded DRM works fine.
Please place an X to the right of the option showing how often you see this issue using specific steps. (Ex: 'Every few times a game is started it flickers.' <- This would be "Often")
Brand and Model of the system.
Hybrid or switchable graphics system?
ie Does it have AMD or NV graphics too?
Intel UMA only
Make and model of any Displays that are used to see the issue (see note2 below).
LFP = Local Flat Panel (Laptop panel)
EFP = External Flat Panel (Monitor you plug in)
Used HDMI Input on HP Omni 27; HP 2711x, and Samsung HDTV all external LCD/Plasma displays
How much memory [RAM] in the system (see note2 below).
Provide any other hardware needed to replicate the issue.
ie: Cables&brand, cable type [vga, hdmi, DP, etc], dock, dongles/adapters, etc
Hardware Stepping (see note1 below).
Operating System version (see note2 below).
Microsoft Windows 7 Ultimate 64Bit
VBIOS (video BIOS) version. This can be found in “information page” of CUI (right click on Desktop and select “Graphics Properties”.
Intel Corp. SYSKLi35.86A.0052.2016.0910.1456 , 09/10/2016 12:00 AM
Graphics Driver version; for both integrated Intel and 3rd party vendors (see note2 below).
Video BIOS: 1036.0
SW or Apps version used to replicate the issue.
Windows Media Center
Single display, clone, or extended (see note2 below).
Display resolution & refresh rate setting of each display (see note2 below).
AC or DC mode, i.e. is power cable plugged in or not?
How to repro
Please provide steps to replicate the issue. These steps are very crucial to finding the root cause and fix.
A screenshot to illustrate the issue is a huge plus. A video of the failure is even better! Attach to the post or provide the YouTube link.
- Configure Cable Card Tuner
- Configure Window Media Center
- Tune HBO HD (MPEG4 DRM)
- No playback video, only audio
- Switch to HBO SD channel, video and audio playback fine (MPEG2 DRM)

Thank you for the information,I will further investigate on this issue, meanwhile try the latest Beta driver that it was released, you can download it here:
Hello IndyC ,
I would suggest you to make sure you have the Digital Cable Advisor installed and run it to make sure the current setup passes all the tests. More details here:
We can look at this and replicate the issue in our lab, but we also need the dxdiag, also we need more details on the streaming setup you currently have (listing all the components involved, from the Cable Card Tuner model, coaxial splitters or Tuning Adapter).
As you said above.
- Click on the “Start Menu” -> Type “DxDiag” -> Press “Enter” -> Wait for the DirectX Diagnostic Tool to finish loading
- In the DirectX Diagnostic Tool, click “Save All Information” -> Save the file DxDiag.txt
- Include DxDiag.txt as an attachment in the Intel Community Forum
