For me it looks like a famous problem when interpreting progressive footage as interlaced when working on it in progressive project.
When you export this you end up with jagged lines (lost vertical resolution). It's quite common on BBC (and not only) masters, seen it many times when working on their content. They were strangely "happy with it".
When it happens in some places maybe these were re-editied etc.

The biggest problem is that there is no good way of fixing this issue. One of the best solutions which I found is to scale these places vertically 2x down and then upscale with NNEDI3 etc.

I would simply ignore it and treat whole thing as progressive. These are simply badly mastered discs with no easy fix.
