 Here is comment 173:

 ''Ticket_11055.m2ts plays correctly and completely by two players that do
 not depend on FFmpeg.''

 ''Ticket_11055.m2ts has 99 frames. All frames are listed correctly by
 framecrc.''

 ''Ticket_11055.m2ts has 99 frames. All frames are listed correctly by a
 packet analyzer.''

 ''Ticket_11055.m2ts.xml data is wrong.''

 ''The showinfo list is wrong. It finds only 53 frames. Its timestamps are
 wrong.''

 ''The show_frames list is wrong. It finds only 54 frames. Its timestamps
 are wrong. It shows DTS>PTS.''

 ''These are facts.''

 ''When are we going to get on with the job of troubleshooting the FFmpeg
 timestamp bug?''

 ''I will do whatever you ask.''

 ''Thank you.''

 What in it do you see that is wrong? Every word in it is a plain fact.
 Prove any of them to be wrong if you can.
