With Windows MediaPlayer 12 you can view via DLNA a video that you store on your PC to a TV (for me a Bravia nx705). The problem is that my TV do not understand so match video formats, so MediaPlayer need to on-fly transcode the video to a supported TV format.
“Windows Experience Index” define if your PC are able to do this job; CPU score gives you the “power” to transcode a native video format to a format that your device may understand and render. Since I’m trying to push an AVI file to a Sony Bravia, the PC attempts to transcode the AVI stream to an MPEG_PAL format that Bravia understands. However, if CPU score is to low MediaPlayer assumes that the PC will not be able to transcode.
To fix it, you need to edit the registry key “WinSAT_CPU Delta” under “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Media Player NSS\3.0\Input Formats\HD Default” from 2.0 to 1.0.
