Because you're using RTCP, the presentation times that come out of 
the "RTPSource" object will (after a few seconds) be *exactly the 
same* as those that that went into the "RTPSink" object.  Therefore, 
if A/V sync is not working for you, it must be because the 
presentation timestamps of the original audio and/or video stream 
were incorrect.

This is a problem that you're going to have to figure out for yourself.
