Global Fix: Windows Media Player audio works, video does not


Hearing sound but not seeing video is a very common problem associated with many versions of Windows Media Player.  The solution is to turn down the video acceleration inside of WMP (not Windows).  To do this, access WMP’s Performance options and slide the video acceleration from full down to medium, or even none if necessary. 

I have seen this issue across my enterprise, and was hoping I could control this setting through Group Policy.  Unfortunately, this is not a setting found in the wmplayer.adm file.  
 
To fix this problem, I used Nir Sofer’s RegFromApp utility to determine which changes are made to the registry when WMP’s video acceleration settings are lowered.  Here is the resulting .reg file, which I pushed out globally to clients via login scripts.  Tested with WMP 9, 10, and 11.
 
Medium video acceleration settings
 
Windows Registry Editor Version 5.00
 
[HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Preferences\VideoSettings]
“PerformanceSettings”=dword:00000001
“UseVMROverlay”=dword:00000000
“DontUseFrameInterpolation”=dword:00000001
“DVDUseVMR”=dword:00000000
“DVDUseVMROverlay”=dword:00000000
“DVDUseVMRFSMS”=dword:00000000
“DVDUseSWDecoder”=dword:00000000
 
No video acceleration settings

“UseVMROverlay”=dword:00000000
“UseRGB”=dword:00000000
“UseYUV”=dword:00000000
