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?
