Changes to .nfo being overwritten

[crusher11 1125]

I have three versions of Aliens. I can only edit one of them in the metadata editor, so to edit the others I have to edit the .nfo file directly. One has different genres to the other two, but every time I edit the incorrect one Emby just edits it right back. How can I make it stick?

Bump.

Go to the line in the NFO. ( the pencil icon next to the movie name) Look at the right end of the Genres line, click the little lock icon to lock that field from being changed.

In the NFO, or in the Emby GUI? If I lock it in the Emby GUI, I would expect that to prevent it from ingesting the change to the NFO, which is the opposite of what I want—not to mention that the whole reason I'm editing the NFO in the first place is that it's a multi-version film and I can't edit this version in the Emby GUI, so locking anything in the Emby GUI won't have any effect on what I'm doing.

Make the nfo read-only in the OS after editing it?
