I've had very similar problems when using a 720x576 screen mode. It
seemed that the shapes used by the theme were scaled correctly for
the non-square pixels, but the fonts were scaled taking account
only of one ratio. You can generate modes that a TV will lock up
on by multiplying all the x vals by a constant factor. Using that
means I tried also 1440x576 (still interlaced). That again gave a
correct layout of the theme but with a very tall thin font. All looked
fine if I used 1024x576. That way you have scaling only in the x
direction (still not ideal), but at least allowing you to use the
TV for deinterlacing (if that is one of the issues).
