Ok Guys and Girls...... I really really don't understand all of this NAS etc to stream music to my SB3. What I would like to do is play music via my SB3 onto my AV amp while the PC is switched off. I did manage somehow ages ago to set it up to play the music stored on my iTunes through my PC but it's not working now. I have bought a WD "My BookWorld" storage device. Is it even possible to use this to store my music on and stream to the SB3? Dave.
