Comment # 46 on bug 7893 from 
Heuristic by default is not what I wanted. Heuristic make user wrong. 
Case I:
1. Someone put MP3 over RTP but set it type to SBC.
2. Wireshark see RTP and MP3, but show type as SBC - BUG!

My implementation make it correctly:
Case II:
1. Someone put MP3 over RTP but set it type to SBC.
2. Wireshark try decode media stream over RTP. Inform user about incorrect
stream. 

By the way: Expert field may be used. Also someone can implementing in RTP
option to use heuristic but not enabled by default. If Wireshark recognize
steam it is ok, but better is detect what is wrong. So I think we all the time
need pass information about stream to decoding layer. We have information so we
shall use it.

Also I will try to say that RTP protocol is not only used as standard
guidelines, but also by everyone. In this case Bluetooth device use it in some
way and Wireshark can decode it correctly, without hack like heuristic.

Michael, do you know something about heuristic what never generate false
positive? (see case II)
