Playback interruptions on Mac OS X

I would suggest making a new thread under support describing your situation and providing all details about your setup. Maybe @andybob can help you get started by splitting this into its own thread.

For Chanjin, his issue was indeed resolved as he discovered what was causing his extraneous network interference. Even though you are having similar symptoms that does not mean that the issues or fixes are the same. Which is why you should start your own thread.
