That's your problem.  You need to start your server's presentation 
time from the current 'wall clock' time (obtained by called 
"gettimeofday()") - because that's what the RTCP implementation 
uses.  If you do this, you'll get the same presentation times at the 
client end.

What RTP payload format are you using??  If you are trying to 
implement an IETF standard RTP payload format, then you can't just 
change the packet format at will.  (If however, you're implementing a 
RTP payload format that you made up yourself, then you can do what 
you like, but of course you can't expect any standard client or 
server to understand it.)
