Is that a rhetorical question? ;-) If not:
If you look at this doc page (or some other related google hit):
and search for teletext, the first thing you will find is the
desciption of the libzvbi-teletext decoder.
It doesn't say right there, but somewhere where ffmpeg's options system
is described, that decoder options are *input* options and belong
before the corresponding input.
The "-fix_sub_duration" is Carl Eugen's special discovery for you. ;-)
He understood the (apparently common) symptom you were describing.

I didn't quite follow in the thread - what is this extra step good for,
and why cannot not be done by ffmpeg in the first place?
