It's not your mistake.  There is a known problem with the current 
"LIVE555 Streaming Media" code: If RTP-over-TCP streaming is used, 
then incoming RTSP commands (after the initial "PLAY") will not be 
recognized by the server.

In the meantime, if you want to use RTP-over-TCP streaming with our 
server, then you should *not* send RTSP commands as 'keep alive' 
indicators.  Instead, you *must* send RTCP "RR" packets.  Note that 
RTCP is a *mandatory* part of the RTP specification, so if your 
client does not send RTCP "RR" packets, then it is not in compliance 
with the standard, and you cannot expect a standards-compliant server 
to work with it.
