I’m also sorry for the inconvenience. "My" numbering system was simply to follow the extras as they showed up on the blu rays, and as they were mentioned in the booklet that came in the blu-rays. At least that what I tried to follow, figuring it would be better to follow something existing order. First time I’ve added extras though, so if there is a better way I’m happy to find out what that is. Other series I have seemed to list the extras in a similar, seemingly random order that follows the order presented on the physical media.

WRT the then extras, where do those come from? None of the three listed on the tvdb site seem to be included in the extras on either of the blu-ray collections.

Your numbering followed mine almost one-for-one. I also did mine from the Blu-rays. I had just broken out a few of the individual items instead of including them together, so my numbering got different early on, but was easily fixed by just combining a couple files and then renumbering the rest. You're good, at least from what I've seen elsewhere. TVDB's specials almost always seem messed up, which is why I've gone to using TMDB's for TV series' especially. People sometimes add way too much stuff, but that's easily solved on the user end by just numbering according to whatever TMDB has them as, and then they get picked up by Plex.

That seems to be fairly typical of TVDB. They always seem to have stuff that is not readily available anywhere. I'm not sure why that is.
