Hello.
This is Lisa Redekop (a University of Ottawa student).
I have two questions for you.

Q1. I have a sample of packets where there is RTSP
on top of TCP, but port 7070 is being used instead
of port 554 (the standard RTSP port).
Ethereal does not dissect the RTSP layer, could you
suggest a way to do this? (point me in the right 
direction <but read Q2 before answering>)

Q2. I thought of "grepping" for RTSP or other words
unique to RTSP and starting a conversation, however
these packets that I'm interested in have a layer on
top of RTSP for which I've already started a convesation.
Is it possible to have two dissectors for one 
conversation (maybe using conversation.old_d, 
conversation.new_d)? And what are the fields old_d
and new_d used for?

Thank you very much for your time!
