...plus apparently every single .mpg file I've ever found on the
Internet, and certainly every one for which I've noticed one way or the
other; I don't remember ever doing -ss in an MPEG file and having it go
to the requested time offset. (Admittedly part of this could be just bad
memory and/or lack of observation... but there have been enough specific
cases that I'd be quite willing to believe the problem is present with
all of them.)
