Disable DXVA2 in Windows Media Center (Windows 7)

You may want to disable DXVA2 hardware acceleration for MPEG2 video in Windows Media Center, for example if the hardware decoding provided by your graphics card is unstable when it encounters discontinuities in the video stream (e.g. interference from passing vehicles with OTA broadcasts).

In the registry, go to HKEY_LOCAL_MACHINE\Software\Microsoft\Scrunch\CodecPack\MSDVD\ If those keys don’t already exist, create them.

Next, create a DWORD within MSDVD called DXVA2, and set its value to 0.
