I also added a 14:9 zoom because a bunch of shows on BBC America are
half-letterboxed with a 14:9 region of the image containing the picture
(with smaller black bars than regular letterboxed shows).

What I've found is that it's nice for avoiding the overscan in zoomed
shows.  I've set the size of the menu windows to avoid the overscan, but
I do playback using the full screen, which looks "right" with regular
shows.  What would be perfect is to have the option to scale the
playback to the UI size, but only when zooming.  Then the zoom modes
would work perfectly for me.
