Well for me it's a graphics card setting, set-up using the
nvidia-settings programme.  I'm afraid I've never used a Mac, so I
don't know what would be available.

I seem to remember that there are some settings in the mythfrontend
setup, related to setting offsets, screen sizes and overscan.  Also an
option to run myth in a window and control the windowsize.  These
might only apply to the menu screens though, rather that the video,
but they could be worth a fiddle with.

It must be a common situation so I'd be suprised if there wasn't an
easy solution.
