Q：
When I play movie on Windows7, always comes this message: The color scheme has been changed The following program has performed an action that requires Windows to temporarily change the color scheme to Windows 7 Basic. Why? There is a solution?
A：
Add the following line to 'mplayer\config' (use Notepad or another text editor): vo=direct3d MPlayer uses the directx video driver by default which causes that and needs to be changed to direct3d or gl. Prefer direct3d over gl.
