 	... that would rather work on fun stuff like mythtv than their 
research, no less... :)

 	It's just a work in progress.  I collected a few more test images.  I 
don't really believe the colorbars' accuracy (not sure if you can even 
*generate* a true colorbar pattern with COTS hardware like a DVD player). 
There's a B&W gamma pattern, and a simple aspect-ratio geometry pattern.  I was 
mainly after the resolution test pattern.

 	Shortly after I announced this a few months back, someone asked for a 
PAL version.  I think I tried to generate it and put it up there.  All of this 
comes with a HUGE YMMV disclaimer... :)

 	Actually, for my own resolution tests, I hacked up a modeline and had 
the computer generate the test signal at 1800x480.  A DVD player at 720x480 is 
not too bad, though.
