[Live-devel] Time to RTCP sync

Make sure that the "totSessionBW" parameter to 
"RTCPInstance::createNew()" is reasonably accurate.  It should be the 
bandwidth of the (audio or video) stream, in kilobits-per-second.  If 
you set this parameter too low, then RTCP reports from the server 
will be sent less frequently than they should be.
