        The issue seems to be with MP4 H.264 encoded content with the copy once protect flag set using onboard Intel audio. MP4 H.264 content with the copy freely flag, or using an external video card seems to resolve the problem. Of course with the NUC using a video card is not an option.

          If the DRM problem is with WMC then why does it work just fine with various AMD and NVidia cards?

           

          I've been running several HP Probook laptops, all with Intel 3000 graphics, and Silicondust Prime tuners. They worked fine until the recent Comcast switch to MPEG4. Now they ALL do not work with "DRM channels". For now, that is only a few channels which I can definitely live without (movie channels). But I fear Comcast will eventually switch them all to DRM.

           

          The issues range from no display/yes sound, the inability to change from DRM to a basic channel, to a blue screen when tuning in to a DRM channel.

           

          I have now installed WMC on a Dell T1500, Win7 x64 with a Zotac GeForce GT610 and no issues with DRM. As I need to now retire the laptops and switch to Dell boxes, I will be trying a couple AMD cards, which I have read have no issues.

           

          To me it is simple: either Comcast is intentionally tweaking the MPEG4 signal to purposefully make user-owned equipment problematic or the DRM/MPEG4 issue is with Intel. It is highly probable that the situation is the latter, despite widespread belief in cable company conspiracy theories. .

           

          It is a shame that Intel will not take even the first steps to resolve this issue. The first steps are obvious: a Comcast account and a tuner. The issue is also obvious: it is with Intel.

            Bryce - you need to talk to your developer. CGMS-A is copy protection for ANALOG transmissions. This connection is all digital via HDMI, so they should verify if CGMS-D is doing what it's supposed to be doing. This is what's required for DTCP (5C) protection. As many have stated AMD and NV graphics don't have this issue. Unfortunately  I running a NUC which I can't add a GPU.

              Bryce - This is definately an Intel issue. I have now in my possession an Intel motherboard with NVIDIA graphics running Windows 7 MCE, and is clearly able to broadcast HBO HD (h.264 encoded) copy protected content. Intel graphics running the same configuration is unable to do the same. There is no changes to other HW or SW. Only the delta being Intel UMA graphics vs. NVIDIA add-in graphics card. You need to ask your development team to dig into this deeper, as it's a clear Intel driver issue.

                I have moved on from Intel HD 3000 laptops to Dell 980 SFF's with Asus AMD HD5450 cards. No issue playing this content.

                 

                The only issue is with fast skipping/backwards. Doing this too quickly freezes the video in WMC but the audio continues. The only remedy is to close WMC and restart it. This may happen during live TV or playing back recorded TV. I've learned to not do this by waiting for a picture to appear before skipping. Fast forward/reverse works fine although not as smoothly as before the switch over.

                 

                I've already invested in the laptop replacements, more time than money, and have no intention of reverting to Intel. I advise all to NOT stay with a system that does not allow you to install other video cards. Who knows what Comcast may do down the road to mess things up even more.

                  Arthur - this doesn't help resolve the issue with Intel graphics driver. What we're doing is proving with data to Intel that the issue is indeed in their court. Both AMD and NV graphics, running on Intel platform w/ Win 7 MCE have no issue with H.264 encoded content. Only Intel graphics has this issue, and they need to address. If some want to migrate over to another platform is their call. @Bryce@Intel needs to take this issue back given the facts provided. Intel doesn't work, while NV and AMD clearly do.

                    Has I agree. But this issue has existed for YEARS. Do you want to wait even longer or do you want a solution now?

                     

                    I'm fortunate to have found one with the help of others before me. I'm offering to others here.

                     

                    Look...WMC is a great piece of software, been using it for years. But, it's not without its issues that require more than the average user's patience or ability to correct and live with. For example, when the program guide was not loading, on several occasions, I finally decided to switch to EPG123 and Schedules Direct. Would you have advised that I wait for MS to fix the issue? Probably. Would they have? Maybe not,or perhaps when the guide was down to one day of data! I now have a solution to that issue that works perfectly.

                     

                    Simply relying on these large corporations to fix unsupported or obsolete hardware/software is fanciful at best. I'd rather move on to real solutions and enjoy WMC while I can.

                      agree - migrating to another platform works - with anything these days, there are nuances. However, Intel should address and not classify this as some other vendors issue. That's all.

                        Update:

                         

                        The following video card has resolved this issue for me:

                         

                        Zotac ZT-71301-20L, Nvidia GT710

                         

                        It also appears that variants of this also work, up to the GT730.

                         

                        I now get no stuttering on live playback/recordings and no issues with skipping forward/back, fast forward/back. The only issue is fast foward on the fastest speed skips too many frames - not as smooth as it was with MPEG2 - I can live with that.

                         

                        Rarely I get a no video when switching from DRM channels in Comcast's 800 range to their 200 range. This is resolved by switching to a non-DRM channel or closign WMC and restarting it (worst case).

                         

                        I previously tried AMD 5450 which had the skipping/fast forward issue. It appears from what others say that Nvidia cards are better at dealing with these issues.

                          OK Intel, This problem just hit my NUC5i2RYH and obviously, I can't change my video card.

                           

                          My OS is Win7 Pro using WMC7 and I am having the same problem with protected h.264 content.

                           

                          Come on guys where is the fixed driver for this?

                           

                          It has been documented for a number of years now and it is increasingly showing up for users, due to cable companies switching to h.264 encoding.

                            Same problem here with my Gigabyte GB-BXi7-4770R, which has an Iris Pro 5200. Comcast in my area just switched a bunch of channels to mpeg4/h.264.  Now I get a bunch of black screens with audio only.  If this is happening only with Intel GPUs but not other GPUs, you cannot claim that this is a 3rd party problem.  It's on you!  Please fix!

                              Hello everyone,

                               

                              Intel is still looking into this situation, and I apologize for it taking so long.

                              Our development team is asking if you can help us gathering some additional information.

                               

                              1. In most 3rd party forums pretty much everyone reports the issue on WMC. Have you tried with a different application (e.g. Kodi)?

                              View topic - Ceton Echo & Xbox cannot play H.264 protected content

                              2. Most 3rd party hardware reported is either HD HomeRun and InfiniTV 4/InfiniTV 6. Do you happen to have a different one?

                               

                              For users with 4th and 5th Generation graphics, please try our latest drivers: Download Intel® Graphics Driver for Windows* [15.40]

                               

                              IndyC and anyone else with 6th Generation graphics, please test with the following driver (Win7): Download Intel® Graphics Driver for Windows* [15.45]. If you already moved to Windows 10, please try this one: Download Intel® Graphics Driver for Windows* [15.46]

                               

                              Thank you for any additional information that you can share with us, and also for your patience.

                               

                              Kindest Regards,

                                Ronald - I downloaded the Win7 64bit driver, still no progress. Again, running on an Intel platform w/ NV GPU works just fine. Only issue is w/ protected content. The blank screen when do quick channel changes is a known issue, unrelated to the h.264 encoded content. Protected channels such as HBO HD are the issue. Protected standard def channels, such as HBO SD work fine (as they are still encoded MPEG)...

                                  Thank you for your patience and all the feedback you have provided so far.

                                  We are actually setting up a test lab to properly debug this issue. Since there is a wide variety in configuration options out there, we are aiming for a basic setup, similar to what is described for HD HomeRun Prime's (except no storage for DVR service):

                                  If you have a different connection structure, please let me know and we'll also try to accommodate to it for validation.

                                  As soon as we have more information I'll update this thread.

                                    @Ronald_Intel - my setup is very basic. Ceton tuner (in my specific case, it's the ETH6 - but same issue exists w/ PCIe version), Comcast/Xfinity TV service w/ HBO HD. You don't need DVR functionality. The issue only occurs w/ H.264 encoded channels, which Comcast is migrating more channels towards. MPEG2 copy protected channels, like HBO (SD) are working fine.  Again, HBO HD (H.264 encoded) works fine when using NV GPU on another Intel platform. My platform is a NUC 6th Gen. So, networked tuner is my only viable option.
