For years MythTV has been regarded as the best media center application for the Linux platform and is extremely popular with HTPC enthusiasts. MythTV is open-source and serves as a digital video recorder with support for reading TV listings and it supports a variety of TV tuners. In addition, through various modules the functionality of MythTV can be extended to be an online photo gallery manager, serve as a music player, RSS newsreader, fetch weather forecasts, and provide quite a bit of other functionality. However, MythTV now has a new competitor and that is Boxee. Boxee is a "social media center" that is based upon the Xbox Media Center (XBMC) with versions for Linux, Windows, and MacOS X. What the Boxee developers have added, however, is a social media aspect to media playback. Whenever you are watching something through Boxee, it will record that information and share it with your friends using Boxee and the user also has the ability to recommend the media they are listening to or watching with their friends. Oh yes, it is also open-source.
