Ridiculous. Why would they remove the ability of the XBOX to act as a pull device and let me browse my files located on another networked device? I can't fathom why they would have removed this. My PC is not in the living room...I don't know too many people who keep the computer that hosts their video files or music files next to their TV. This is a massive step backwards in functionality...please come up with an app that will act as a media browser and let me pull via DLNA, like the XBOX 360's video player will.
This decision was a giant head-scratcher, to me. At least they didn't eliminate it completely, the way Sony did...but come on. Microsoft has gone to great lengths to make media consumption in every other way easier, yet they've actually managed to make DLNA LESS convenient than it was, before.
