Exactly.  Now one button doesn't do it.

I think what we need to do next is set up a wiki page about what kind of
zooms / aspect changes we want / need, and make sure we can find a solution
that covers all of the bases.

Personally, I don't have a Myth setup (yet) on a 4:3, so I don't know what
kind of stretching / compression that screen may need.  We need to be
careful no to exclude their needs.  Once we can figure out what we want, we
can see what would be the easiest way to implement it.

I kind of like the idea of maybe a program based zoom.  Several of my
programs are always sent in 16:9 ratio onto my SD feed, and it'd be nice if
myth remembered my favorite setting (no aspect change, full zoom) for
viewing them.
