[mythtv-users] mplayer couldn't open x11 display

[Michael Gargiullo]

Hey all, 

I ran into a small problem. Fresh debian / Mythtv .19 install. When I
attempt to play a movie (mpg or divx), Myth just blinks, and returns to the
movie's info screen. I logged in as mythtv, and attempted to launch mplayer
with the same settings (minus fullscreen and quiet) and got the following
error:

I've tried using every sane vo listed in mplayer 

Code: 

@mythtv:~$ mplayer -vo help

I've googled without success. 

The strange thing is if I capture mpg video from the tuner card. 
Code: 
cat /dev/video0 > /tmp/test.mpg 

I can play it fine with the same mplayer play command. 
Code: 
mplayer -vo vx -ao alsa /tmp/test.mpg 

That works! This is nuts.

I noticed there was no display listed in the error... So I setup the
environment var DISPLAY to mythtv:0  (the host name).

Tried again:

vo: couldn't open the X11 display (mythtv:0)!

Does anyone have any ideas?  I'm going nuts.
