No you can't, because - as I explained earlier - RTCP is used not 
just for packet loss reporting, but also for audio/video 
synchronization.  It adds very little overhead, and you have no 
credible reason not to implement it.  Just create a "RTCPInstance" 
for each "RTPSource" object in your receiver.

That might work initially, but over time, you will still need 
information from RTCP Sender Report packets to do proper synchronization.

Once again - RTCP is *not* optional.  But fortunately, it's supported 
easily in the "LIVE.COM Streaming Media" code.
