Comment (by budman1):

 You are kidding right? I succeeded in creating a segment that has frame 0
 dts/pts timecode of 0.000000 for better merging. Players play segment
 starting with frame 0 (1850).  You cannot extract frame 0 (1850/1851)
 because ffprobe displays the first frame as being crystal clear, complete
 frame, audio in sync 'B' frame.

 Bug is: Players view frame 0/1 (1850/1851) so they are included. ffmpeg
 cannot extract those frames because according to ffprobe they do not
 exist!

 One more item: 25 FPS and 29.97 FPS work correctly.  30 FPS does not.
