As I told before, I had a ransomware attack (Deadbolt) on my QNAP that killed most of the videomaterial and the folder jpg. I deleted them all, and am in the process of rebuilding the collection. TVR keeps a list of what I once had, which is a great thing. An extra little, thing which I believe is relevant: A number of folders still contain the nfo file I got with the video.
When I do a "movie search", the number of "missings" listed in the search is only a really small subset of the db entries where I don't have a video file.
My ASSUMPTION is that the "movie search" lists "missing" as the db entries where there is no folder. An empty folder might be deleted, but in my scenario, given the nfo, the otherwise empty folders aren't deleted. These entries don't show up in the search as missing.
(4.8.3 videos found in the search folder are added every time I do a search).
