In trunk SVN #25210

http://svn.mythtv.org/trac/changeset/25210

(it should backport to 0.23 just fine)

While it doesn't perform a full resolution + refresh rate match, it
does now let you change to *some* custom resolution as well as refresh
rate.

Myth will now perform the following check in this order to find what
the best display mode is:
1- Exact width, height and refresh rate
2- Exact width, height
3- Exact height (ignore X entry)
4- Exact refresh rate

Action #1 to #3 is for the list of custom rate (up to 3).
Item #4 is for the default video output resolution.

So if you want to have the TV play everything at 1920x1080 using the
best refresh rate but 720p content to be played in 1280x720 using the
best refresh rate
You would have:
Video Output: 1920x1080 Rate: Any

Overrides for specific video sizes:
X:0 Y: 720 Output: 1280x720 Rate: Any

To force all 720p content to play at 60Hz
you would have:

Overrides for specific video sizes:
X:0 Y: 720 Output: 1280x720 Rate: 60.000Hz

I guess re-reading your post, I could perform an extra step, of
checking the refresh rate only with X=0 and Y=0 in the list

But another day...
