Plex Home Theatre is designed to be installed on a dedicated computer (PC, Mac and Linux versions are available) connected to your TV, and allows you to access your entire media library and enjoy it on a big screen. It offers built-in support for local storage (on your PC or network attached storage) as well as for content stored on Plex Media Server. Additionally it will play movies and TV shows streamed from all the major providers out there.
Plex Home Theatre also allows you to easily organize your media into specific categories (such as 'TV Shows', 'Comedy', 'To Watch'...) making it really easy to always find what you are looking for. It will also inspect your media library and automatically download any missing metadata such as titles, release dates, and so on from TheMovieDB.
As well as having some great features, Plex Home Theatre has been designed from the ground up to look great on a TV screen and is compatible with most IR controllers making it really suited to frequent use. This may take some getting used to if you're used to other home theatre software, for example Plex Home Theatre doesn't support traditional usage of the mouse buttons. But once you get used to it you will never look back!
