Because

	1) Ethereal can only handle RTP, not, for example, any of the
	   proprietary Real protocols;

	2) if an RTSP message specifies a transport Ethereal can't
	   handle, it prints out a message.

The latter can be fixed by removing the code to print that message -
it was probably intended only as a debugging message.

The former might be a bit more difficult to fix, as per the word
"proprietary" in that item - Real don't document that protocol publicly,
as far as I know, unless the Helix source does.
