According to the Xbox 360 forums, in Connecting the Xbox 360 to stream media without media center you will see your shared folders appearing under Music, Pictures and Video in the Media blade of your dashboard. Those who have already run the Media Center guide, but want to play the music in games as well, will also need to use this guide.
MEDIA PLAYER 111. On your 360, remove the existing connection to another PC, if you have one, by going to the Settings blade, then Computers. Don't remove the Media Center PC if you have that set up.
2. On the PC, open Media Player. Add all your files to the Media Library, by clicking on the arrow below the Library button and choosing "Add to Library". You can either search or manually choose folders.

4. All things going well, you should see the Xbox 360 listed as an extender device. Select to allow all media through to the 360. Press
OK.
5. On the 360, choose Music, Video, or Pictures. You should see the name of your PC on the right-hand side of the screen. Select it. After a couple of seconds, your media should start to appear.
Once you've connected either Music, Video, or Pictures, you won't need to repeat the process. The 360 will configure all media types.
