Se usate mplayer.exe su Windows 7, magari preso da http://sourceforge.net/projects/mplayerwin/files/latest/download?utm_campaign=updater&utm_medium=email&utm_source=subscribers e all’avvio di un filmato avete uno sfarfallio del video con il messaggio “The color scheme has been changed“, nessun problema, ecco la soluzione:

Aggiungi la seguente riga al file “config” all’interno della directory “mplayer” (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.
