Then you can stream internet radio or even live TV from your computer.
Source:Stream internet radio to the Xbox - Xbox 360 & Xbox ForumsCode:Not sure how well known this is, but there is a program called Tversity that acts as a media server for remote devices. It also officially supports the Xbox 360. The primary reason I started using it is because it transcodes Internet Radio streams to a supported format for the 360. And of course, you can listen to the streams while playing games. You can also use it to do everything Windows Media Player does, plus much more. All those formats the 360 doesn't support are transcoded by Tversity into a supported format. TVersity - Home I spent many hours figuring out how to get it working so I'll include a quick start guide so you don't repeat my mistakes: 1) Download and install Tversity Important: While installing and prompted to use ffdshow, select all available formats. IOW, check every checkbox possible. 2) Add an exception in your firewall for port 41952 (TCP) 3) Disable media sharing in Windows Media Player. Tip: Open Windows Media Player, click on Library | Media Sharing | Uncheck 'Share my media' 4) Download radio playlists from Shoutcast.com (Rename to whatever you want - by default they are named 'shoutcast-playlist.pls'). Tip: narrow your search with the term 'HD' to filter HD-only stations and right click on 'Tune In!' and use 'Save link as' 5) Add the playlists in Tversity by clicking Add | File | Browse 6) Refresh Media Library in Tversity You don't need to change ANY settings in Tversity That's it!!! I've even uploaded my playlists and named them appropriately: http://www.phpstory.net/files/Streams.zip Just extract them to any directory and add them via Tversity. Enjoy!!
