    Upon installing the Windows 8 "Hyper-V" feature (the platform and management tools), all flash videos in Chrome and desktop IE cause the application or the plugin to stop responding. The audio will play but any attempt to interact with the window or the video causes the application to crash.Also powerdvd mobile can't play any videos and vlc plays videos only in green.I use hd 4650 card the probelm persist with both microsoft defaut driver and amd legacy driver.Which componet of Hyper-V cause the corruption of DXVA ????
    Any idea to solve this ???

    Only activate Hyper-V when you use it.

    There is no such video crashes after enabling Hyper-V on Windows 8 x64. Tell us all specifications of your system and software installed. Which codec pack are you using?

    Hyper-V is not built for viewing video. It is meant to be for a virtualized workspace.

    Have you read the title of thread?

    He is talking about hardware accelerated video crash on system after enabling Hyper-V, not about video crashes in Hyper-V. Moreover, Hyper-V interact with hardware directly, so there shouldn't be any problem in playing hardware accelerated videos. Also check MS blog, where MS guy demonstrated hardware accelerated demos of Internet Explorer 10 running in Windows 8 Hyper-V.....:cool:

    Right!
    My ati 5750 in notebook not accelerate also the h264 movies with Hyper-v enable, I suppose it is normal because win 8 not run in native mode but inside an hypervisor.

    ATI drivers are usually troublesome. BTW, it is MPC-BE with custom optimized codecs with GPU acceleration. It is working flawlessly here with lot of modified settings (Configuring MPC-HC for GPU Accelerated Video Playback Guide) :)

    same here with AMD E-450 APU. (even with latest driver 13.2 beta7)

    DXVA stopped working after activating Hyper-V which is needed in Windows Phone 8 SDK.

    I thought it was an obvious bug since the day Win8 has been released, and it hasn't been fixed yet till now..
