After buying a 3D TV and starting to enjoy quite a few movies in 3D, I miss the fact that Plex doesn't distingush 3D from regular movies.Right now, if you have a 1080p and a 480p version of a movie, Plex will prompt you to choose one. What I'd like is a way to hint that a movie is in 3D and possibly what type of method that is used for 3D (Over and Under, Side By Side, etc...).
Maybe as simple as renaming the file so it ends with .3D. or what have you. This way, when you look at the movies in PlexWeb, a 3D logo will be present and when you start to play, you get an option to choose the 3D version.
