It's a media server for Linux, Windows and Mac. Download and install the server and point it at your media folders and it automatically downloads all the metadata for your media. In conjunction with the media center for Windows, Mac and Android, it delivers a stylish skin and hardware acceleration for all your high definition video. Best of all, it's free. I'm very impressed and thought some of you might be interested, enjoy.
