I have just tested what I said, and it does not works exactly this way. I know 
I should do the contrary, testing, then talking... :-)

In fact, mplayer accepts being embedded into a window, but it hides the window 
it is embedded into without letting QT seeing that. So this window must be 
hidden and shown each time a movie starts, to force the window to be visible 
!

Moreover, the window passed to mplayer must no redraw itself.

So I have modified the DrawingArea widget so that when it is disabled, it 
draws nothing on the screen.

I have wrote a MoviePlayer example that will come with the next version of 
gambas.

Regards,
