Mplayer GUI not working

[anafshalom]

I've been using mplayer for a long time with several distros, and I like it.
I'm running Fedora 16 with XFCE 4 on a 64 bit machine.

I can use use mplayer from the terminal and it works fine:

reuven@ReuvenFedora:/$ mplayer -fs -playlist [path/filename]

But when I open the GUI interface, when I hit play the window which displays the video dissappears and I hear the sound, but no picture.

Any ideas how to fix that?
