It does work. I did it this morning when I was getting ready for work.
First the phone and the xbox must be on the same network cuz thats how dlna works. If your xbox isnt connected to a router it wont work.
2. Once the xbox boots to the menu, go to your phone. Go into the stock music player and play a song. Now hit the menu button to the left of the hone button. Scroll through the menu and select scan for nearby devices. It should find it. Now back on the music player screen you should see a little computer icon looking icon at the top left. Tap that and will automatically connect to the xbox. At this point the xbox will change screens and the music will start playing.
3. Once the initial connection is made you shouldnt need to do it in the future. So if you turn off the xbox and then back on your phone should automatically find it. Once again you must press the icon on the top left of the gn2 music player app.
4. As far as video goes, this is thoroughly depending on quality of connection and router network speeds. My phone stored torrents play just fine with zero lag. However ONLY video formats supported by xbox will play.
