Hello,

My GPU:

Intel Graphic HD3000 @ Core i5 2500K

My Video settings :

Renderer : DXVA
Allow Hardware Acceleration (DXVA2) -> ON

Basically, whenever I play x264 encoded videos, after every few seconds, the screen would produce distortions to the point of the video being unwatchable.

Is this an issue with the drivers ( I tried the most recent one, and a few editions back, but still the same) or that the implementation isn't mature enough?

Intel and DXVA2 do not play well together - there's lots of folks waiting for driver updates from Intel.

I'm getting the same problem. I switched from ubuntu to windows to make the wife happy and I get this when I want to watch full Bluray rips... I didn't have a problem in ubuntu tho. sigh

DDDamian · 2012-03-24, 16:47

Ubuntu doesn't use DXVA which is DirectX (Windows) Video Acceleration.

You can blame on Intel for that, and they're always behind on GPU. I wish that they bought Nvidia when they had a chance.....

Damn, so in order to get nice and clean playback I would need a dedicated GPU? This build keeps getting more expensive

Just switch DXVA2/GPU Accelleration off. Your 2500K is MORE than enough to handle decoding by itself.

No need to spend more money if you dont want to, the main point of GPU accelleration is to save power/CPU runtime, but if you're just running XBMC by itself, and don't really care about power...then there's no reason not to run this way. Smile

My kid i3 laptop can playback fine with DXVA2 disabled. If it work fine without DXVA2 enabled, you don't need it......but it's nice to have it working though.

My other HTPC's with AMD GPU are working fine with DXVA2 enable... Nod

Was there ever a fix for this? I posted in a few different forums and I see now that it is a hardware issue. My original question is posted below.

I was wondering if I can get some assistance with an issue I'm having. I have an Ultrabook I am using to add to my network of XBMC machines. The Acer specifications are listed below. My other machines are hardwired and work with the default XBMC settings. Also, they are i7's. The issue with the Acer is that during playback the screen periodically distorts really badly. See first image. Originally I thought the issue was that I was streaming my content via wireless and it couldn't keep up but that was not the case. After light troubleshooting it seems there is an issue when the throughput gets above 40 Mbps (number attained using windows resource monitor). Any assistance would be appreciated.

Things I tried

Connecting Hardwire - Same result periodic distortion. See second image
Connecting via USB 3.0 - Same result periodic distortion. See third image
Using a different movie - Distortion not as bad but still an issue.
Changing network drives - Changed streaming from the MyBook Live to the Synology NAS. No difference.
Changed XBMC Settings - Turned off "Allow hardware acceleration (DVAX2)" - The distortion stopped but the picture stutters and audio periodically drops out. Sometimes when it comes back it is out of sync.

Also check just to be sure that in the control panel of ur graphic card (nvidia or CCC or whatever), Video (or video color) is handled by the player instead of by the card.

Thanks! I will try that and see what happens.

Hey hello! I have the same problem on my HP Envy X2 Laptop/Tablet running plain Windows 8, if i turn off hardware acceleration the movie plays but very choppy and stuttery.

The downloaded movie plays in the standard Win8 player & WMP just fine but not just not in the lovely XBMC Sad

I did try to update everything but the latest driver for the Intel-Graphics-Media-Accelerator-GMA-3650 isn't supported for Windows 8, the current one i have installed is from 8 jan 2013 however. Version 9.14.3.1130
