I'm not sure if your last two comments are supposed to be connected or
not.

What you are calling "hard-coded SD" is *non*-anamorphic
letterboxing. Most widescreen SD DVDs are encoded as anamorphic
images - the wide image is "squeezed" from the sides to fit into the
disc's native 4:3 frame and the TV electronically "stretches" the
image back to its normal proportions. The advantage is the you get
more actual resolution from the disc - the full 480 horizontal lines -
than you would if the widescreen image were hard-matted within the 4:3
frame, the way widescreen VHS tapes and laserdiscs had to be.

A few early discs, and a few later ones where the studio cheaped out
and just used an existing LD or VHS transfer instead of going back to
the original film, are non-anamorphic. Most of these were eventually
re-issued as anamorphic transfers. But some never were. In my
collection I have "Scream", "The Mask", "Streets of Fire", "The
Rocketeer" and the "bonus" discs with the original versions of the
first three "Star Wars" films that were that were grudgingly included
with one of the releases of the "SW" Special Editions. I have to
change the output settings on my DVD players so that I can zoom these
films to the full width of my set. You'll probably need to do the
same.

When using component, I get a 4:3 display even when it squishes a 16:9 source. <

OK, if this isn't referencing non-anamorphic discs, then you simply
have the wrong output option selected for your component out, the
wrong aspect ratio option for that input selected on the TV, or the
combination of the two is mismatched. A film of a given aspect ratio
is going to fill exactly the same amount of the screen on the same TV
regardless of medium, source, resolution or anything else, provided
the set and the source are properly set up.
