I had the same problem and then I ran into this link--->
'GameSpot Forums - PlayStation 3 - How to setup Media Server'
(
http://www.gamespot.com/pages/forums...ic_id=25653426)
it cleared everything up for me. now my media centers are shared. if
the issue continues, you might try messin with your firewall settings a
bit to allow "windows media player" related content to access your
computer. hope this helps.
