@AntcuFaalb - Forgot to mention in my first post that this is an awesome project you're undertaking. But just as valuable is the detailed description of your methodology. Much appreciated!

If you have seen this bootleg can you say whether that process would be possible/desirable with this capture as is?

Haven't watched it; my bandwidth is the proverbial "98-pound weakling". :) My reply was strictly according to TServo2049's description of the anomaly (which is likely considering the "old VHS bootleg" context). I would say that the correction is desirable and workable (I've manually tested this in the previously mentioned RJSR circumstance). Also, the correction should be automatable in, for example, Avisynth, as such an anomaly would have been machine generated.

^Spaced Ranger in the scenario you describe, would it look something like this? So far I'm not seeing that in PS78v0.1. Fields look pretty-well blended there but I suppose it could be the result of DivX encode, as AntcuFaalb said.

Your frame doesn't quite look like what TServo2049 was describing. Your frame has part of one field is shifted, not double-exposed to give a "smeared" appearance. (Of course there's no motion here.) I've separated the fields of the frame. Switching between them shows what is happening to that one field:

This could be an alternate manifestation of the same anomaly, where the anomalous part is not double-exposing, instead superseding. A review of 5+ sequential frames (preferably with moving subjects or background, but not both) should make that determination.

On the other hand, this could be the result of AntcuFaalb's equipment-chain interacting to produce a new anomaly. Maybe TMTBC (Too Much Time Base Correction)? :)
