Turn on your PS3. Your PS3 and the PC you will be using for streaming must be connected to the same network.
Open Windows Media Player 12.
Click on the "Library" option from the upper toolbar, then select "Media Sharing" from the drop-down menu.
Check the "Share my media to:" box.
Select the "Video," "Photos" or "Music" menu on your PS3, depending on which files you are going to stream from your Zune. Select "Scan for media server."
