[MPlayer-users] new mplayer user

[debian]

Hello!

I am a new Mplayer user and i'm looking forward to use Mplayer
exclusivly! Really nice program!
So, i installed the beast yesterday on my linux system with the codecs,
gui and it is working fine...
subtitles and everythong are okay.
There is only one problem, when i start a movie it is shown in a window
and when i go to fullscreen, my screen goes black and it show the movie
but the size of the movie is still the same size like it was in the
window.
the same when i select double size.
So, the problem is that the size always stays the same.
What could this be and how can i solve it ?

cheers,
Phil
