Hate to tell you this, but there are a limited number of broadcast
quality encoders out there (and a couple of them (at least used
to) license the same IP to do the encoding), so it is highly likely
that many use the same encoder.  It is usually not the encoder,
it is the choices that the broadcast engineer makes.  The
broadcast quality encoders have "billions and billions" of knobs
to tune to get just what one wants.  Some engineers (essentially)
leave things near the defaults, others will adjust to achieve what
they believe is best (and in encoding, "best" still has some
very subjective input).
