Yes, but it's likely that John (I think I snipped the attribs right there)
was talking about people -- and there are many Just Like Us -- who are
still tuning *analog* from a cableco. We, too, get downconverted SD analog
from the center 4:3 of the signal -- which is why many producers still
protect for it.
And yes, those downconverters are often really stupid about incoming
pillarboxed 4:3 pictures in the 16:9 signals they receive, leaving us
with *dual-letterboxed* pictures.
