using Particles and creating a particle for each title.
Have they changed/improved in MC20? I've only ever done them in MC19.
I use them for full disc rips of TV shows, but so far all the ones I've done have been 'out of order'. Take a full disc rip of American Horror Story Disc 1, that creates tons of particles so I have to go through and bin all of the short ones - it had loads of like 10 seconds here, 13 seconds there, etc.: clearly not episodes.
That left me with the correct number of particles for each actual episode. So I assumed particle 1 would be episode 1, particle 2 episode 2, etc., so filled in the tags accordingly.
We then watched episodes that were recounting things we hadn't yet seen - we watched episode 5 thinking it was episode 5, when in fact 5 and 6 had been switched so we unknowingly watched 6 first, with it recounting stuff from 5 - so I had to have Wikipedia open on the laptop doing a live commentary in my mind while watching episodes to make sure they were right, and if they were wrong I had to re-jig the episode numbers and re-do 'Get Movie and TV Info'.
Same thing for all discs of Season 1 and 2 (3 blu-rays each).
