goonies never say die
I hope someone can help. My sister was watching a DVD on her iMac DV/SE and every once and a while, there's a static clicking sound that comes from the speakers. She has a USB hub connected to one port and an iSub sub-woofer connected to the other USB port. What is causing the popping sound and is there a way to fix it? It is really annoying when you are trying to watch a DVD.
