If I have 5 movies (ie. all the Harry Potters), my iTunes organizes them by alphabetical order, but I want the Harry Potter movies to appear in sequential order.
Under the Get Info area for each movie, is there a way to number them or something?
You need to set a sorting name, for example, Harry Potter 1, Harry Potter 2, etc... You can set the sorting name from the Sorting tab when you get info on the movie.
It also appears that if you have your TV preferences in iTunes set to stream only, then the TV does not pay any attention to the sort fields. But if you set your library to sync, even if your not syncing anything, then the sort fields are honored.
