How do you organize box sets for tv-series/movies?

[Wotan]

For tv shows do you just add the dvd's/episodes etc in the comments box? And for a movie box sets, do you just add the box set? Or add each movie as an entry, but how do you know which movie belongs to which box set?
I was just curious to how people did this

Was there a follow up to this, I have quite a few and would like to be able to get online information.
