Build Information:

--
When sending an MpegTS over RTP to wireshark, packets are default decodes as
UDP.
When doing a "Decode As RTP", actwards (via Telephony - RTP -) RTP statistics
are persented, with 6,2% packets loss.

When DISabling protocol "Mpeg PES" ,  0% Packet loss is presented.

The "lost packets" are related to "Malformed Packets" when "Mpeg PES" encoding
is enabled. 

Althouh i doubt if the mpeg pes is really "malformed" (will investigate this
later), my opinonin is that RTP statistics, must NOT be depended on lower level
decoding !

All Packets on RTP level are available, whith correct seq.numbers, so
packetloss of 6% when enabling lower level protocol, seems very silly, and
incorrect.
