Leo,
When you saved your extract, Ethereal no longer has the context of the
RTSP packets to know which UDP ports have RTP on them. (RTP can
basically run on any UDP port - different vendors have different ranges
that they use).
To view your UDP packets as RTP, simply right click on one of the UDP
frames and select "Decode As..." and then seclect the approriate port
(usually the destination port) and choose RTP in the decode as list.

Subject: [Ethereal-users] filter the RTP packets
Dear Sir/Madam,
I filtered the RTP packets from the original trace file and saved to
another file, but there is only shown the UDP packets in filtered file.
How can I keep the RTP packet in filtered file?
best regards,
leo
