Wireshark appears to be incorrectly flagging the PMT as malformed in the packet
capture I have. Manzanita MP2SAE (Commercial MPEG Analyzer) does not flag the
same PMT when I extract the MPEG TS from the capture and run it through
Manzanita.
Attaching sample packet capture and Manzanita report. You will see many of the
errors if you use the filter ip.dst_host ==239.0.1.94 && _ws.expert.severity ==
error
One specific example is in IP packet 406, which contains a PMT in MPEG packet
2439. Wireshark is flagging this as malformed, however it does not appear to
actually be malformed.
