And if the receiver does NOT use Live555?

OK, I do use an RTCPInstance.
What does "correct" in this context mean? I record the first incoming 
presentationTime for the first outgoing frame and add a constant value 
(correspoding to one frame duration) to it for every following frame. Is 
that "corrrect"?
