Thanks Michael, but I suspect we could make progress without insulting 
each other.

Again, I have only superficial knowledge of the MPEG TS spec, and I am 
not _at all_ trying to impose anything on you experts. At the same 
times, the TS muxer is broken today (not playing on STBs), and the 
superficial symptom I see seems (with my limited investigation skills) 
to involve the PCR.

Of course I can just shut up and go back to reading the standards, but I 
had hoped that one of you could kindly explain why my suggestion is 
idiotic. And currently I have a workaround, relying on VLC's muxer which 
doesn't suffer from the same shortcomings. Hence my motivation posting 
here  (which you can of course dismiss) is to bring back ffmpeg's tsmux 
on track, and not to offend anyone.
