Grabbed pattern from link posted by trevlac -- if this grayscale is similar to what you guys were playing with, cool. Of course it won't show color effects of compression, but maybe do some good.
Had some minor issues with file color space of original, but nothing that would effect anything and tried orig & conversion anyway.
Compressed to mpg2 & DV, tested losses -- while detectable, not that significant. As I mentioned earlier, and maybe it's unusual, I've done a lot more with stills then video, so that's where I'm most comfortable when not trying to measure transients. The DV format showed very slightly more degradation then mpg2, with a very, very slight shift in red which I would have expected. The biggest difference was in the vert moire to the right in both cases.
Interpreted RGB output to small TV monitor was good, though a bit limited because just plugged composite in, with a slight bit of interlace flicker on horiz. lines in upper and lower moire. DV & mpg2 showed some degradation, DV was noticably worse on pattern in left lower circle -- right lower did not display properly in amy case, but again that was expected.
DVD test to TV with 600+ Horix. Lines Res. was interesting.
Everything checked out except 1 pixel wide horiz lines, again as expected. These would have mapped to alternate fields so moire did it's dance as I assume it was designed to with it's alternating bands of white etc., as explained here (Find the word "wedge" towards bottom of page):

Don't know if that helps or not...
