Do HDTV sets eventually convert all incoming HDMI signals to analog
before displaying them? Or do they convert all incoming component
signals to digital?

if your tv is of the lcd/ plasma variety with a pixel for pixel display,
there's no need for analogue.

If the display is analog, then all signals get converted to analog
eventually. If the display is digital, then all signals get converted to
digital. What you might not like happening is analog to digital to
analog conversions happening inside the display.

Ultimately, everything is converted to analog, even though in some kinds
of technology that could be right at the very edge of when the signal is
becoming a modified level of light. For example, if a pulse width is
used to control a light intensity at some pixel, that is still analog in
the time domain, even if the signal is only on or off in the intensity
domain. That's not really any different, logically, than a stair step
of voltages when converting digital to analog in the intensity domain.

If you are wondering if there is some set of wires inside the display that
have the video decrypted, uncompressed, and converted to analog, where you
could tap in and capture the analog to convert back to digital, compress,
and record, the answer is maybe. If you are willing to accept video that
is in some other form besides conventional analog, the chance of having
such video in a usable form would be greater.

Ultimately it all becomes analog (whether in the intensity domain or the
time domain ... the latter of which depends on your eyes to integrate to
the appearance of an intensity domain). Different technologies do it in
different ways. Legacy CRT technology is most likely to have wires you
could tap (if that is your motive, which I do not know that it is).

A possible practical question which could get people to wondering about
this kind of thing is: how do I play a DRM protected DVD/HD-DVD/BR-DVD
to more than one display simultaneously (because the family gathering
during the holidays is a bit too large to huddle around one TV, even if
it is a big screen)? HDCP apparently cannot accomplish that (because
the movie industry wants to gouge consumers by forcing them to buy extra
copies of the same movie for such family gatherings).

And you are ignorant about physics. That was obvious many, many posts ago.

The OP ask a question about D/A A/D conversion as it pertains to component
vs. HDMI and you launch into what can only be described as a fit of mental
masturbation. Reading your reply was like watching 20 minutes of a deer on
ice, I was eagerly awaiting (not) your discourse on string theory. Sometimes
it's good to remember when dealing with none Mensa members to (KISS) keep it
simple stupid.

Not to mention that he is wrong in several places. He could have looked
up his facts before posting nonsense on the internet, but it appears
that poor old phil is too lazy or stupid (probably both) to do that.

Thank you. That answers my question.

You sound like one of the professors I had in college. He had a
doctorate degree. He was very smart. Unfortunately, I flunked his
class because I didn't have the slightest idea what *he* was saying,
either.
