I'm running the stream on the laptop which is running windows. I had it on briefly upstairs on my iMac and I think that same thing happened. I wasn't paying close attention, but all of a sudden I realized that my upstairs stream was about 1 song behind downstairs. That may have been the same symptom. unfortunately, that doesn't help. it seems to be running fine at the moment. nice "the weight". Mr. Helm sounds great. He's got a fantastic lineup of musicians. Allstar cast really.
