I am desperate... Please help me with this problem
Every time I launch a YouTube video in Safari [5.1 (7534.48.3) / Lion OS X 10.7.1] the YouTube page is served and the video starts (sound included). With a short delay a second audio stream of the same video is served. When I stop the video player, the second (i.e. the delayed) audio stream continues. After closing the browser tab the audio stops. I can demo this with this URL http://www.youtube.com/watch?v=n6oXZSQeGbk , but any YouTube URL will do. N.B. No other video playback apps are running and there is no difference when using Flash or HTML playback.
What can cause this behaviour and HOW do I get rid of it?
