[MPlayer-users] Full screen mode

[Rodrigo]

Hi can anyone help me out
I'm using Geforce 4  PCI 64 MB  533Mhz Celeron initially Redhat8 
upgraded to 9 with yum.

When performing the command " mplayer -vo x11 filename.avi "
I can see the avi sequence without a problem with an amazing good 
quality :-) much better then on XP

the problem with this command is that I can not see the file in full screen

When trying to open the same file  with the Mplayer GUI I always get the 
error

" Error opening/initializing the selected video_out (-vo) device.

Can any one help me ?

Regards,
Rodrigo
