While I am not a lawyer I happen to be in the middle of a patent
At least in the jurisdictions I know about, and I think it is the
same everywhere in this regard, using patented methods at home
for personal use is NOT a problem. You are allowed to use a patented
home for your own use as far as I know and thus they are not relevant
to users of vdr.
It is commercial use that patents deal with.
On the other hand...
Decryption technologies have been protected in different countries
with EXTRA laws precisely because the normal existing laws did not stop
people from using their own data once they paid for it.
As far as I know, the US DMCA (Digital Millennium Copyright Act)
is the only really strong law of this kind that is current (NOW) in
believe it prohibits you from decrypting and decoding any information
the manufacturer did not want
to to decode, regardless of how easy this is.
I believe the related EU Copyright Directive (EUCD) has not been fully
approved yet, due to concerns from
some member states. I might be
wrong though, as I have not heard anything about it for a while.
It is also a very restrictive law based on pressure from WIPO.
This is a complicated law and I do not pretend to be an expert on it,
but I have heard enough
informed opinion to know it is very restrictive and, in my opinion, if
you take it literally is it is a
severe limit on personal freedom in the interest of corporate profit.
I believe it's limitations include decoding (i.e. playing) a DVD that
you may have
purchased yourself on a device that does not have the licensed software
(for example a linux box). It was recently used in a (US) court case
to stop a company from enabling
Lexmark printers to use 3rd part ink containers since it involved
opening the boxes. I think it is possible that if you modified the
firmware in your computer and/or video card, you are in violation (if
you live in the USA).
Note that while the DMCA is very restrictive, not that many people
have been taken to court under it,
as far as I know.
