So sorry, how does this say they are coming from lots of independent rips?
I guess that could be true today since decss is so available, but I presumed
that short of that, we still just get one rip and everybody would copy
that until a better one came along etc. The point being it doesn't
matter much how hard it is to rip as long as a modest number of people
can do it, because all the unskilled folks can perfectly copy those

So far, AFAIK, nobody has built a watermark that was both invisible to the
viewer and which could not be removed.
What is the motive of those who build TVs with analog inputs to have
them detect the watermark? That does not serve their customers. Only
if they need a licence for something else that they can't get without the
watermark detector, would they have a motive to do this.
That strikes me as an antitrust violation, but who knows? Because there
is no much motive, that's why we saw the Hollings Bill / CDTPA.

This again is a view I have a hard time understanding. The key factor
about analog copying in the old days was that each generation was worse
than the prior, so after a few generations, VHS was useless.
D2A2D, on the other hand, introduces just one generation of analog errors,
and after that copies are perfect, and by and large with good A2D, hard
to tell from the original.
(In fact, I would say that with audio today, we have sound cards able to
sample much faster at higher res than CD resolution that people could
not tell an well done audio recording that was from D2A2D from the pure
digital. That will be true for video some day too.)
So again, help me understand the reasoning over why D2A2D is not just
as much of a concern as difficult pure digital copying to the DRM groups?

Huh? By 1995 I thought everybody in Hollywood had figured out the VCR
was the best thing to ever happen to them.

No that makes sense. I did not mean the 5C meetings were this, I was
describing the sense of the negotiations between Hollywood and the tech
Why MS gave it is one that puzzled me for a time. Bill Gates has more
money in his wallet than Hollywood makes in a year.
That's where the real suspicion of hidden agenda comes in. Microsoft's
agenda against its competitors and Linux is not hidden, however. If
they can make it so the media plays on Windows, but not on Linux or a
Mac or smaller competitors, it's a big win for MS.

If people want. Frankly, I think discussion of the issues can be a welcome
break after endless volumes of messages on how to configure your pvr-350!
