first you have to allow windows media player to share your music. second to have to add all the music and videos and pics to your librbary inorder to see it on your ps3. when you search for wmp through ps3 make sure media server is enabled and you have to forward ports inorder for it to work.
also on windows media player go to share media tab and allow devies to connect to windows media player.
here is the link to the ports you have to forward
it took me awhile to get it right also
hope this helps
