Users on my network complain that my music rarely connects or when it does it streams or buffers almost constantly and a full track cannot be played. No other users on the network seem to have this problem. All other users are using the PC version of iTunes and I seem to be the only one with an Apple system. I'm sharing my library off a Powermac G5 1.6ghz that seems to run pretty quick to me. I'm also connected to the network via aiport extreme card. Any solutions?
