RE: [MLUG - DISCUSSION] DVd saga... over?

Okay, here's the question. If the VCR removes the macrovision, then if I
connect straight up to the TV, I will be blocked from seeing the content I
have viewing rights to. Correct?
So the TV has to remove it. If I have an older TV that was bought before
macrovision, and so it does not have the filter hardware, I must buy an
external filter. Wait a second, what are they going to do? Make me buy a new
TV? This whole thing seams kind of stupid. If I were to record the
macrovision signal completely, I should be able to repeat it in a way that
behaves as the original, and defeats the "Copy protection".
Don't these people understand that natural law precludes copy protection.
Man can't dictate laws to govern nature. Nature is the final authority in
all matters, and there are no loopholes. :-) If we ever find a way to
"Break" a law of nature, it's not that it has been broken, it's that we did
not understand it well enough in the first place. And always remember " Do
not try to bend the spoon with your mind. That is impossible. Instead, try
to realize, there is no spoon."
I think the problem is that people have not dealt with these concepts
before. There are some laws in information theory, but they bury them. Every
one knows that matter and energy can neither be created or destroyed, but do
they know that some problems are not computable, or why. The proof of all of
this is a little complex, but the principles are not too difficult. At the
same time, I'd like to put forward the theory that any thing that can be
viewed can be recorded, barring quality issues determined by the resources
available. Any thing that can be recorded can be reviewed by putting that
information back into the system at the point it was removed, unless the
recording becomes destroyed or corrupted after the fact. Time could become a
parameter, but then if it's a parameter, it would have to be part of the
definition of the point where the signal was removed and should be put back
into the system. I don't know. Do you think it's a sound concept?

I've always assumed vcr's were /smart/ enough to know to remove
Macrovision from what is being sent to the tv but not if it's being sent
to the tape. Macrovision is fairly easy to remove but it is frowned upon
in the same was DeCSS is frowned upon, It does distort your picture/sound
clarity in some cases though so it is legal to remove it from media you
own for your own viewing.

I'm not familiar with all the details but remember tidbits caught ehre and
there and remember a schematic for a Macrovision filter I saw in a howto
magazine that was simple enough that even someone new to electrnoics
should be able to build it.
