I tried using -XX and -s1500 like it was advised by
Peter, but the problem persists : I have the content
of the PPP Compressed packets, but I haven't the
content of the RTP packets not compressed.
 My work consists on compressing a video stream before
sending it and I capture the packets to analyse them.
 So, I want to have the compressed and not compressed
packets details. but I have only the content of the
compressed packets in hexa :(
