When it comes to displaying multimedia content on a computer Microsoft pretty much has a stranglehold on computers. There have been a few linux distributions to try and take on Microsoft but so far there is only one that has really been successful, XBMC Media Center.
Originally designed for the Xbox, it has grown and is now available for multiple platforms. Linux, Windows, Apple TV, OS X (Power PC and x86), and even Live versions are available. The Xbox version is no longer publicly available (due to legal reasons) but if you search Google you can find it via third-parties.
