I've been using restore24 since I'm not sure there is any alternative. The only think I can possibly think of is to manually pull the good field and resize. Then locate all field shifts myself manually.

Anyway, at the moment it looks generally good. The occasional blended field survives (but I believe in some cases it's unavoidable.)
What I'm running into now that I strongly dislike is (and I haven't figured out if it's the source or Restore24) that movement is unnatural.
Occasionally a moving person/object will jerk forward like a frame is missing.

My first step is to figure out if the frames in question actually exist in Mentor's version... then, hmmm, yeah.
