No idea where I picked the 568 figure from... thanks for that.

Spot-on -- thanks!

A fcouple of follow-on questions:
1.So does Myth re-scale everything to whatever your actual Xorg
resolution is? I've got something like 704x544 to deal with overscan.

2. I can adjust my TV using the service menus to get rid of the
vertical overscan (but not horizontal), but it seemed adjusting my
Xorg was the 'correct' way to do it. Can I instead use the TV's v.
overscan control to maximally shrink the picture vertically then add
lines back to my xorg to get a higher vertical resolution? This would
be really useful when switcing to Gnome to use other apps. Or will
this damage my TV?
