I think I might have found a solution to my own problem.  I'm looking 
for some confirmation and high probability of success before I do the 
big scary upgrade from Ubuntu 7.04 to 7.10.

I'm the guy with two x-session. I only use Myth on one at a time, a 16:9 
projector and a for 4:3 TV.  I think this should work.

for 16:9 projector:
mythfrontend -O XineramaMonitorAspectRatio=1.7778 -O Theme=blootube-wide 
-display :0.0 --geometry 1280x720+0+0

for 4:3 TV:
mythfrontend -O XineramaMonitorAspectRatio=1.3333 -display :0.1

Note the " -O XineramaMonitorAspectRatio=1.**** " bit.

It also seems that I should be able to add this to my xorg.conf and fix 
the problem there too.
Option  "Xinerama" "false"

Thanks I value any upgrade advise I can get,
