It appears I am not alone. I have similar problems although with perhaps a different twist. Utilizing the media player in Xbox I can play movies and play music contained in my Windows 8 system. But this only holds true if that is the first action I take upon opening my Xbox. It I do something else first, as an example play a game, I can neither play a movie nor listen to music on the Xbox. This is strictly a Windows 8 issue as I don't have a problem with my Windows 7 system nor Vista system. I am surprised this issue has not been corrected. I don't suppose Microsoft is trying to steer us into spending money on the Xbox music system or movie rentals?
