[mythtv-users] Getting mplayer to play nuvexport files fullscreen

[Ben]

I've exported files for archiving with nuvexport, however when  I play 
them with mplayer, they appear 'square' and only  take up about 60% of 
the screen (two large black bands on either side).  How can I get 
mplayer to play the files to occupy full screen?
The original files  were captured in 720 x 576  with DVB-T, and I can 
see from the mplayer logs that they are encoded as 720x576 mpeg2.  I did 
read somewhere that mplayer needs DGA & SUID and a matching video 
resolution of 720 x 576 in order to be able to play without scaling.  Is 
this correct? However this resolution is not available under x ( xorg 
log).   The mplayer documentation is not clear to me on this.
Can anyone help please?

Cheers Ben
