I only record 4:3 SD content with my Mythbackend. My problem is that without
telling Mythfrontend what the display aspect ratio is, it stretches the 4:3
content to fit (I guess assuming that the display is 4:3 - this is without
any zoom applied).

The same version of Mythfrontend running on my MacBook Pro offers the
ability to change the display aspect ratio (as I mentioned in my initial
post). This option is not available in the UI on the Mac Mini.

If there is another pref I can twiddle I'd love to hear it. I'm also game to
try building the frontend from scratch if there is a lower level
patch/config that will do what I want.

Thanks for the clarification, I wasn't sure whether Mythfrontend was calling
through to the native windowing system or using X11 on top. Regardless, it
does seem to use the  XineramaMonitorAspectRatio settings parameter to
modify the its behaviour in some cases (as demonstrated by my MBP).
