If everything is properly configured you should get pillar bars on the
sides of the screen. What seems to be happening is that for some reason
your system is not able to determine the size of the monitor. This has
nothing to do with the modeline the monitor uses. What you need to do is
tell xorg to ignore your monitor edid info and manually specify the size
of the screen in xorg.conf. Set the dimensions of the screen to 128x72
and myth should be able to correctly scale your picture and menu text.
The wiki has good info on this.
