I have a Radio playlist, which I control, like the rest of my library, via the Remote app on an iPod Touch. I get frequent "hangs" on rebuffering, which I can only fix by force quitting iTunes. It happens most when I first switch to a station, but it sometimes happens in the middle of streaming. And it happens far, far too often, especially since I run a headless Mac Mini and have to go to another room to access it via screen sharing. Any suggestions?
