[Red5] sound sync

[Interalab]

Anyone have any ideas about how to prevent audio from getting out of 
sync with video on the client end?  What's happening is that a client 
will connect to a live video stream and after a while the audio is out 
of sync by a 1/2 second from the video.  Refreshing the page (reloading 
the flash movie) reconnects fine and is in perfect sync.  That says to 
me that it's a client side buffering issue.  Any thoughts from anyone?
