*bump*
Though Blitz is the only release in a MKV container, the others are OGM; a-S and Blitz are the only XviD releases, the rest are DivX.
Otherwise the specs seem to be about the same (well, Legacy is a bit unclear), so it would depend on video/image comparisons.
Archivisth has the a4e release, so could provide screens. Perhaps TheProfileth can provide Legacy and CvP a-S screens?

Blitz is rather unavailable I'm afraid, I've been looking for that one for quite some time.
