Ok; good to know that a real server respects the meaning of standard
RTSP commands :)

Uh... So, you found a bug in QTSS (you are saying that it replies to
requests for unknown protocols saying that it supports them, righ?)

Yes; you can use hints from the SDP (I think the payload types are
more meaningful than a "IsRealDataType" line for which we ignore the
exact meaning) to select the transport protocol(s) for the SETUP
request.

After that, the transport protocol used for parsing the incoming
packets is determined by the SETUP reply coming from the server.

You mean, sending a list of acceptable protocols instead of
repeating the SETUP command multiple times? I think this can
wait (let's avoid to introduce too many changes simultaneously).
