Thanks for the suggestions, Reimar, but they didn't really get me much 
further.

Well, not in my application. Sure, if I resize the containing window (in 
my case a wx.SplitterWindow) and then play the movie from paused, it 
will rescale to fill the window, but I want it to rescale as I resize 
the window with the splitter. This latter action works when I use "-vo 
gl", so I am happy enough. Incidentally, my argument list is:

args = [self.MPLAYER_PATH,
                    '-nofontconfig', 
                    '-slave', '-idle',
                    '-msglevel', 'all=5', #default all=5
                    '-nosound',
                    '-noconsolecontrols',
                    '-fixed-vo',
                    '-vo', 'gl',
                    '-vf', 'crop=448:416:108:112',
                    '-wid', str(self.window),
                    ]
I load my movie files elsewhere in the application using the slave 
command 'loadfile' through a named PIPE.

If I remove "-fixed-vo" from my list of arguments, then I end up with 
black screen when my video finishes instead of the final frame showing.

Thanks anyway. Best regards,
