Cool!  I think you'll see pretty quickly why interlaced display never 
caught on for general computer use... the flicker it introduces is 
pretty distracting.

Have you tried 480i?  For such content (standard-def TV), does your TV's 
deinterlacer do a better job than Myth's?  I realize a desktop this 
small could be pretty painful...

I can see two solutions:
1. Write or modify a theme for MythTV so all horizontal lines in the UI 
end up at least 2 pixels wide.  I think text would be the hardest.
2. Add code to use different X resolutions for GUI vs. video display. 
In fact I could see the usefulness of being able to use different X 
resolutions for different video formats.  The 'xrandr' command is 
capable of switching resolutions in a nice way, for a suitably recent 
versions of XFree86.
