I guess it was this Wikipedia article that lead me to believe 601 is for DVD or Standard definition:
https://en.wikipedia.org/wiki/Rec._601
While it doesn't specifically say anything about DVD's, it says it is the standard for ISO/IEC MPEG (which is what DVD uses), and the bottom of the article for "See Also" says Rec709 is for HDTV and Rec2020 is for UHDTV.
So I guess my question is, if a DVD doesn't have any color space tags, should it be assumed to be 601 (470), or 709?

The dev version you sent (2020.09.25-195552) shows Rec601 on RGBAdjust for both input and output now on first load and on reload.
On the x264 tab, it shows bt709 for -colormatrix on first load, then changes to bt470bg on reload.
Comment in AviSynth script says on both first load and reload:
Still not sure if DVD should be 709 or 601!
