I have 2 AppleTV's. Different rooms, different receivers, eveyrthing. They BOTH have started recently just stopping playing video and send out a loud BUZZZ/SQUEAL out of the speakers, and all I can do is unplug them. It's not heat related, both are well ventilated, and in totally different rooms and locations. Just now, they BOTH did it within 1 minute of eachother. Both were streaming from iTunes 10 on a mac pro with SL. I store no videos on the AppleTV units, I stream it all from my computer. Anyone else ran into this? Is this an iTunes 10 problem? I find it hard to believe I am having simultaneous hardware problems on 2 different AppleTV units, within 1 minute of eachother. This has happened a few times now. I also have to relaunch iTunes on my Mac Pro for the appleTV's to reconnect to the library. What is up with this? Anyone seen this?
