Unless there are very new drivers that I am not aware of, Intel HD 2000/3000/4000 Graphics (GPUs) cannot display Cox's Copy Protected H.264 Plus Pak channels using Windows Media Center.

I think new drivers were released in December to correct just that issue, but please correct me if I am wrong.

I am running those drivers and they did not fix the issue for me. Anyone else?

Product Detected - Intel Processor Graphics 3000
Current Driver Installed - 9.17.10.2932

Driver Package version 15.28.12.64.2932 (9.17.10.2932) for Windows 7

Well the release notes seem to state that issue is corrected, but I don't have any of the hardware yet to test. I was still in the planning phase of my build. So I will take your word on it. So there is no driver different between the Intel 3000 and the Intel 4000?

Which particular fix listed are you referring to in the Release Notes?

Mine is a 2nd Generation Intel Core i3-2105 Sandy Bridge with Intel HD Graphics 3000. The drivers are the same for 3rd Gen however.

I was refering to two seperate items, but your right, its not clear.

"Resolved issue where video output is missing content when transcoding certain video files"

"Fixed protected content playback issues for new Windows 8 Store video players like Netflix*."

Is the issue that the drivers ignore the copy-protection flags while processing H.264? Also, most markets still use MPEG-2 right?

I am not sure what the issue is exactly, there is Audio but no Video.
Error Message:
"Display driver error" and "does not support playback of protected content"

No, I believe every market is now H.264 (MPEG4-Part 10) for the Plus Pak.

Most any other Graphics card works fine. Even past Intel mobile graphics, like my old laptop work.

I am just going by what google tells me, so take it with a grain of salt but:

"Also, if you are using embedded graphics of Intel CPU, you can't watch these channels if they are copy protected. Intel graphics drivers do not support copy-protection and H.264 at the same time."

And looking at the next post

"Surprisingly, my new windows 8 laptop with hd4000 ( i7-3517U )-plays the protected h.264 content from cox just fine... windows 7 on the same machine using the latest drivers from intel does not and usually results in a blank (black)..."

So I think the fix ""Fixed protected content playback issues for new Windows 8 Store video players like Netflix*." fixed the issue, but only for Windows 8. However the data is not clear. Would need a dual boot with Windows 7 and 8, same hardware, to really isolate. If nothing else though, its a pretty good hypothesis.
