Hi,

I am experiencing quite noticeable juddering/stuttering on Netflix (most noticeable in scenes which pan across the screen) on my HTPC. I get the same results in both their web player using Chrome, and in Windows Media Center. Yet when I watch the same content on my iPad Air, I do not see this juddering/stuttering of the picture at all.

Do others have this issue? What could be causing it? I have a GeForce GT 610 graphics card in my HTPC. Could this be underpowered?

Cheers.

Try monitor your GPU when playing a video, it sounds like its using the CPU.

If it is using my CPU, is there a way to make it use my GPU?

There is probably a settings file somewhere.

Ok does anyone have any helpful suggestions? Does no one here experience juddering/stuttering in Netflix on their PC/Windows Media Center?

I've done lots of Googling on the issue and the latest theory is perhaps the frame rate at which your PC is set to. I read that most, if not all Netflix content is streamed at 24fps. Could this be my issue? If so, how do I reduce the frame rate on my Nvidia graphics card?

What sort of CPU do you have? I remember ages ago when I had a WMC and an AMD CPU, and a good GPU, I had to install the drivers for the CPU otherwise the picture in video was really jagged and jerky. Once the driver was installed it was fine.

Also for a while I fixed it by changing the CPU affinity to 1 instead of 2 for the WMC.exe (this was on a dual core CPU). But that had to be done each time I rebooted, so the driver install was the long term fix.

Hi gehenna,

I have an Intel Core 2 Duo E8400 CPU in my HTPC. I experience no other jerkiness (live and recorded TV and Sky, playing all sorts of video files etc). Would you think a driver update migh solve my issues?

It was only 720p video and above that I had problems with, and Blu-ray disks. Once I updated it was fine. Worth a look maybe.

I don't think my CPU has any drivers as I can't seem to find any.

I've been reading further and it may have something to do with Netflix's 24fps (23.976 to be exact) vs our 60hz TV refresh rate or something. An option is to turn my graphics card down to 24hz (is this even the same as 24fps?) but then what will the rest of my content such as live TV look like? I haven't had a chance to try it yet and am a little reluctant to stuff my system up...
