Comment (by tracey_pooh):

 ... and sorry if "critical" is Big Alarms -- I meant to explain why I
 picked that.

 We at Internet Archive try to help our PEG (Public Access, Education, &
 brothers and sisters and are transcoding for some of them (as well as
 video archiving).
 The good folks at Seatle Community Media alerted us to the fact that none
 of their
 programs were being "accepted" by their Televue hardware systems suddenly
 my Mar 21 ffmpeg build.   It eventually led back to this bad muxrate in
 the pack header
 causing Televue to reject the mpeg2s that we make.

 Best I can tell, this muxrate is wrong for every MPEG2-PS created by
 so hence the "critical" selection.   Apologies in advance if that was too
 extreme.  8-)
 Rock on, ffmpeg!
