Sorry to bump this old thread, but it's a good thread, and it's relevant to something I've been researching here and on the Web and can't find many suggestions on: how to organize TV shows.
I've used the automator scripts generously shared by Mac.Jedi to rip, encode and tag several hundred movies and a couple of thousand TV episodes. I watch them almost exclusively on the ATV2.
Figuring out what to do with movies released in theaters and regular TV series is easy. But I have a lot of DVDs and Blu-Rays that do not neatly fit into one category or another. Many of them are documentaries from PBS, BBC, Food Network, History Channel, Discover, etc. Some of them are in series or mini-series. Others are one-off specials.
For example, what do you do with a TV documentary that consists of only one episode and is not part of a larger series? A lot of times those are found at the themoviedb.org rather than thetvdb.com. I have generally listed these as TV shows, making them episode 1, season 1 with the show name and episode name having the same value. This means that a single episode gets a whole show and season to itself.
Some of these have been set up on thetvdb.com as a series such as "History Channel Documentaries," into which all the one-off specials are grouped. This solution works OK, although it seems a bit artificial to treat all these documentaries as being a single series.
