I have seen strange behavior like this before with rtp packets and
ethereal. If ethereal doesn't see the RTSP session that establishes
the stream then it won't know to associate the RTP protocol with the
UDP RTP packets. Depending on the rtp payload and port, ethereal will
sometimes miss-identify the packets as other protocols. If you make
sure that ethereal sees the RTSP session, then it should automatically
pick up this association. Otherwise, just right click on one of the
rtp packets (if you know the ip and port) and select "Decode as..."
and pick the protocol manually.
