I have reprogrammed the recording button of my X50 to toggle screen rotation. The direction of the rotation seems to depend of the last rotation setting used in 'Screen' icon in system tab in settings. Now my screen rotates counter-clockwise from portrait to landscape, the way I prefer.

However, I have also set WMP to play video in full screen mode. The problem here is that when playing fullscreen, WMP rotates the screen clockwise to landscape contrary to the rotation direction used by the programmed button. Every time this happens, I need to press the programmed rotate button twice, first to return to portrait and then to landscape counter-clockwise.

Any suggestions how to force WMP to rotate the video counter-clockwise always?
