Because Ethereal became RFC3550 compliant:

-----------8<------------
   The RTP payload type (PT) constants are defined in profiles rather
   than this document.  However, the octet of the RTP header which
   contains the marker bit(s) and payload type MUST avoid the reserved
   values 200 and 201 (decimal) to distinguish RTP packets from the RTCP
   SR and RR packet types for the header validation procedure described



Schulzrinne, et al.         Standards Track                    [Page 69]

RFC 3550                          RTP                          July 2003


   in Appendix A.1.  For the standard definition of one marker bit and a
   7-bit payload type field as shown in this specification, this
   restriction means that payload types 72 and 73 are reserved.
