Yes, the four files are (with Gordian Knot parameters)
Input rez: NTSC; Input PAR: NTSC 4:3 (both with and without ITU checkbox)
Input rez: NTSC; Input PAR: NTSC anamorphic 16:9 (both with and without ITU checkbox)

That gave me every combination. I got the aspect error on 3 of the files to be a perfect 0.0%. I think one of the ITU checkbox files had to settle for 0.1%, because I kept the W-Module at 32 and the H-Module at 16, which limited choices.

It has been mentioned by other users that unless you watch a DivX movie in full screen, it won't set the correct DAR like a DVD player. I watch most of my DivX movies in a window anyway, but I remeasured the circles full screen and didn't see much of a difference in AR, if any.

I am not discounting the vast knowledge of TheWEF or Manono, but just need my results explained to this layman!
