Hi Duane,

Xebian 1.0 is suppose to work with xbox 1.5 and up. It only works in 640 
x 480 at this point (from what I hear). It is the only version that 
supports the focus chip (I think).

Have you tried to adjust overscan with xbv? ssh in and try 'xbv -auto 
640 480 4.0 4.0'. The last 2 parameters are the horizontal and vertical 
overscan values. Adjust them until you are happy with the size of the 
screen.

After using xbv, you will have to disable double buffering with 'xvattr 
-a XV_DOUBLE_BUFFER -v 0' from an X session. Otherwise Myth runs very slow.
