There is a checkbox inside Myth Frontend that says to run the GUI in an
alternate resolution from the recordings.  Once you enable this
functionality (it uses xrandr to switch resolutions on-the-fly), you can
define alternate resolutions based on the input resolution.

If you configure x.org to have a GUI-specific res, a 720p res and a 480i res
(i.e. something like "Modes 1366x768_60 1280x1024_60i 800x600_60", you can
then configure Myth to switch between them automatically based on the
recording resolution.  When you restart X, run "xrandr" and you'll see all
the available resolutions.  To switch, just specify -s # as CLI arguments to
xrandr.

As an example from my workstation:
> xrandr
 SZ:    Pixels          Physical       Refresh
*0   1280 x 1024   ( 433mm x 347mm )  *60
 1   1280 x 960    ( 433mm x 347mm )   60
 2   1280 x 800    ( 433mm x 347mm )   60
 3   1152 x 864    ( 433mm x 347mm )   60
 4   1280 x 768    ( 433mm x 347mm )   60
 5   1280 x 720    ( 433mm x 347mm )   60
 6   1152 x 768    ( 433mm x 347mm )   55
 7   1024 x 768    ( 433mm x 347mm )   60
 8    800 x 600    ( 433mm x 347mm )   60   56
 9    640 x 480    ( 433mm x 347mm )   60
Current rotation - normal
Current reflection - none
Rotations possible - normal
Reflections possible - none

If I want to switch to 1024x768, I enter "xrandr -s 7".  My display
immediately changes.
