When I open a video file with WMP, I get this strange message (see picture). Despite the message, the video plays correctly though. This message does not occur with the WMC or VLC.
The message comes regardless from which HDD or SSD I play the video. So it cannot be a disk driver
problem. My Display adaptor driver and my Monitor driver (HP w2207h) are on the latest level. And there are no yellow triangles with any other device in Device Manager.
I don't know where to look any more. Any suggestions?
PS: "Web Help" is useless.
