So i went to espnradio to listen to the live stream today and noticed that it would no longer play on my 3 month old 1.67ghz powerbook g4. So i tried copying the url from the page source and no dice. so i also went to another site and tried to watch some streaming video, there was no sound but the video was fine. and i tried a flash site (homestarrunner) and no sound. But all he quicktime content works fine. (all these apps work on my mini) any ideas?
