So, my new MBpro is having an issue where Air tunes gets choppy, cutting in and out. Only happens when there are other devices (computers or iphones) accessing the network and the new MBpro is playing music over air tunes... It does not happen if my old PowerBook G4 is the host computer playing the music. Any thoughts? Config: Time Capsule is the host. Airport Express is a slave Old and busted PB G4 works fine (still) New hotness MBpro 3.06 is choppy when playing with others.
