I’ve been again attempting to add some Documentaries that I’ve loved and want to share. Editing the metadata for files as been difficult at best and because there seems to be so many possible ways of doing this I wondered if I could quickly describe what I’ve done and see if this is the way 
Here are some filenames (mp4) that I’m using:
TV Documentaries library:
Equinox {tvdb-125741}
Equinox - s1994e03 - The Cyborg Cometh {tvdb-4384882}.mp4
Equinox - s1994e11 - Rave New World {tvdb-2442801}.mp4
Horizon {tvdb-74379}
BBC Horizon - s0000e05 - Beyond the Moon {tvdb-1394091}.mp4
BBC Horizon - s0000e60 - Extinct- A Horizon Guide to Dinosaurs {tvdb-4176295}.mp4
BBC Horizon - s1980e26 - Anatomy of a Volcano {tvdb-1018771}.mp4
BBC Horizon - s1978e09 - Now the Chips are Down {tvdb-558681}.mp4
BBC Horizon - s1982e03 - 25 Years in Space {tvdb-1387151}.mp4
BBC Horizon - s1984e02 - Microworld! {tvdb-1393871}.mp4
and…
Vangelis and the Journey to Ithaka (2013){tt4047898}.mp4 -can only find the IMDB ref 
Hack The Planet (2001){tvdb-6299997}.mp4
On The Edge Of Blade Runner (2000){tvdb-4735992}.mp4
Everybody In The Place - An Incomplete History of Britain {tvdb-147075}.mp4
<< None of these above individual shows, show up at all - not sure why?
At first glance, is the syntax correct for these shows? I’ve tried to follow *[Naming and Organizing Your TV Show Files | Plex Support] as some parts seemed relevant.
Any of you nice people attempting to add shows like this and have more effective ways of doing this? I could REALLY do with some solid pointers as I feel most of the time I’m throwing files into the air and seeing what then sticks correctly.
What software are you all using to change the metadata on your movie files? (I’m using a Mac)
If I knew how to amend this I’d be a happier chappie
