Your PlayStation isn't just for games. With a few tweaks to your settings and some software set up on your computer, you can stream music, videos and photos from your computer(s) to your PS3 over your home network.
Set up your PS3
Step 1: Make sure your PS3 is connected to the same network (via Ethernet or wireless) as your computer. You can check your connection by going to Settings > Network Settings.
Step 2: Go to Settings > Network Settings > Media Server Connection on your PS3 and set it to "Enabled".
