Jittery playback from WMC recordings due to known 29/59 framerate issues

[CBlon]

My problem is I am on Comcast and have issue with the 29/59 ( http://support.microsoft.com/kb/2658140 http://support.microsoft.com/kb/2658140 ) frame rate changes. Jittery playback with the recording seeming to only playback a frame every few seconds. I was able to fix in win 7 computer by disabling Film Mode Enhancement and Contrast Enhancement in Advanced and Skin Tone Enhancement in Basic. My win 8.1 laptop with a intel hd4400 tried the same in the video menu for intel and turned off those but still have the issue.

And here is the problem described by ceton

This is a well-known problem with Windows Media Center and occurs across all OCUR devices. The problem is the result of an incompatibility issue between Windows Media Center's decoder and the MPEG steam encoder, especially when Windows Media Center receives video which does not properly indicate its framerate. Some video encoders used by cable operators attempt to detect the framerate (in order to minimize bandwith) and get it wrong; the framerate is re-detected every few seconds, resulting in a rapid change between 29.97 and 59.94.

Unfortunately, every time the framerate changes, Windows Media Center must re-set up the video pipeline, resulting in the color flickers you see on your screen. Ceton formally requested that Microsoft fix this issue. Unfortunately, Microsoft made the decision that the amount of work it would take to resolve this issue was too great for them to invest in it at this time. The official Microsoft Support article on the issue can be found below: http://support.microsoft.com/kb/2658140 http://support.microsoft.com/kb/2658140

It seems like there is still auto enhancements turned on but not sure what else to change in video settings or else where as I have a sony Vaio i7-4500U intel hd4400 and a Nvidia GeForce gt735 which I believe is inactive with WMC running. I did manage to get same recordings on my i5 2500K desktop running fine by changes mentioned above but the vaio laptop is still giving issues on playback.

Any other Ideas to help?

FYI this is only a problem on recordings where the frame rate rapidly changes as in a syfy or history channel recording. My cable provider is Comcast. ABC amongst others don't seem to do this. According to other forums and my experience this is a playback issue not a recording issue.

Add me to the list of people with this problem:

Problem I am having is most premium channels (HBO Showtime) stutter and jump around very badly to the point of nausea at times. I really want to reduce or elliminate this behavior as other graphics manufactures have been able to. The channels that display this behavior are the ones with the "bad" metadata causing the 29/59 flipping.

System:

Gigabyte ga-z97n

Intel i5-4690k

16 gig ram

Intel Driver Version : 10.18.10.3960

I turned off adaptive contrast via the registry keys.

I have not able able to figure out to smooth out the video where the 29/59 bug is concerned. I thought the darn thing was broken as this is replacing a 5 year old icore7-860 system that was just sucking too much power with nvidia gtx750i. This system posed no issues with the bug, I have only found out about it since moving to my new setup.

Please provide a solution as I hate to think I spent all this money on a shiny new system to make it smaller quieter and more efficient only to not be able top use it. The only PCIE slot I have is loaded with the ceton 6 tuner card, so new gfx card is not the answer.

Can someone from Intel update this thread with the progress? I and many other have this problem. I have a Core i7 4790s running Windows 8.1 Pro with Media Center.

Hi, Hansb,

I'm already on that driver and it hasn't resolved the issue. Was it supposed to?

Thanks

Hello JeanClaudeVanDamme,

That driver did fix some bugs with the graphics, but since the driver was not included in this thread I wanted to make sure that you had tried with this one. I'll let the engineers know that the issue is still not fixed.

thank you.

[JVanD]

Thanks, Hansb,

I'm keeping my fingers crossed that they get this resolved soon. Can you confirm with them that they have successfully reproduced the issue?

[JVanD]

Hansb, have the engineers been able to reproduce the issue?
