[mythtv-users] SVid Out Problems(PowerStrip & xvidtune)

[Jim Oltman]

I have tried xvidtune, telling it to widen the screen and move it up. 
The numbers change, but the screen does nothing.  I have also tried
loading windows on a seperate hard drive and running powerstrip with
no joy.  I can change the numbers so far then boom, screen goes ape. 
But up to that point, the screen doesn't move.  Does xvidtune and
PowerStrip only work ong VGA/DVI out?  How can I move the screen
around with out using OVERSCAN in Xorg and not using the
nvidia-settings tool?  Thanks!
