Comment (by markfilipak):

 Replying to [comment:186 MasterQuestionable]:
 > ͏    As for FF-series tools' misidentification, would it because the
 peculiarity of this file:

 The question I ask and have always asked is how can framecrc and showinfo
 ever be different? At what point in the logic of showinfo does it change
 the value of TSes? At what point, and why?

 The next question is how can framecrc and show_frames ever be different?
 At what point in the logic of show_frames does it change the value of
 TSes? At what point, and why?

 The next question is how can showinfo and show_frames ever disagree?

 Logic dictates that all 3 functions should report the exact same TSes: The
 TSes that I created. Why? Because they are the only TSes that exist.
