[Bug 157099] Re: Automatic installation of DVD CSS support

2007-11-28 Thread Jared Blecker
Under the DMCA its illegal to develop, distribute, or use any tool that
can break or bypass an encryption, which the libdvdcss2 library does
just that, bypasses the CSS encryption system.  Now there are certain
exceptions, like security research, and the question is whether or not
libdvdcss2 being used to only play back legally purchased DVDs on Linux
because no other method exist, is a valid exception.  This question can
only be answered by passing legislation that modifies the DMCA or having
a court decision saying that the libdvdcss2 library is a vaild exception
to the DMCA.

For the time being, I believe Ubuntu should handle this issue in a user-
friendly but legally safe manner.  This is what can be done when a user
inserts a DVD with CSS encryption:

Tell the user this disc cannot be played because of the CSS encryption
Tell them that there is a library called libdvdcss2 that can be used to play 
back their DVD
Tell them this library isn't included in Ubuntu for legal reasons, and that it 
can be found in third-party repositories

You missed the part describing the compatibility clause in the DMCA
and how libdvdcss may fall under it and how with a be of legal
research we could be sure. So far I take all advice as hot air from
technical people that are not lawyers.

2007-11-27 Thread Stephan Hermann
Guys,

every year and now the same discussion.

The problem is not the software itself, but what it is doing.
css2 decryption is illegal in many countries of the world, and therefore it's 
hard to distribute this piece of software.

It's not because of the license

Try to use non css2 secured DVDs.

As long there is no legal safteyness for distributors like Canonica,
RedHat, Novell/SuSE and others to distribute this and as long there is
no legal safteyness for Users, this is a no go.

Are there? as far as I know there are legal saftyness in the DMCA, but
no one will put any lawyers onto finding out so we're all just
scratching our heads as programmers and businesses without a damn clue
other than a guess. I've even had it said to me that libdvdcss is
legal in the EU which is probably isn't since the EUCD is potentially
worse than the DMCA.

At least, explaining the issue to the user like Conrad proposes is
required: else, you think it's a mere bug. It could be good to provide a
link to a page on Ubuntu's website developing the legal issues we
encounter and giving links to tutorials about installing it. DVD
playback is essential, and silently refusing to read them makes Ubuntu
ridiculous for new users.

To go further, installing deCSS libs should be made as easy as possible:
just installing a package should be enough, no even needing to use the
command line to start install-css.sh after that.

[Bug 157099] Re: Automatic installation of DVD CSS support

2007-11-27 Thread Stephan Hermann
@Marting,

I don't think it's legal in Europe. But I could be wrong. TBH, but I don't care.
If it's not legal in any country, means, in all countries of the world it has 
to be legal, my wish is that no one is able to install it with apt-get install 
libdvdcss2 from Ubuntu.

Further, it's not ubuntus fault, not even marks or anyone else, that the DMCA 
or the EUCD is blocking this.
You want Linux to play your propietaery encrypted DVDs? Please go to your 
representative of your EU or your US dictator, and tell him that you are 
infridged in your freeness to play rightly bought DVDs.

If those people understand what's up with you...this problem will be
solved asap.

The other method would be, write letters, not emails, to your local
sony, toshiba, phillips, bertelsmann (aka sonopress, which is one of the
biggest DVD resellers) etc. distributor and tell him, that you don't buy
any DVDs they will sell or produce. If anyone in your country is doing
this, libdvdcss2 will be freed like no other piece of software from the
ubuntu or debian ftp-master.


Regards,

\sh 
PS: There is no need for buying encrypted DVDs.

2007-11-27 Thread Malte Cornils
Since even pointers to libdvdcss2 et al. are murky legal territory,
maybe it would be a useful feature to at least detect a DVD's usage of
the CSS system and show a note stating legal restrictions and so on
(ranging from Sorry, we can't help you and Try an unprotected DVD to
Petition the EU parliament here: click and Buy legal DVD player
from third-party vendor (Linspire's Click'n'run, ...) click).

2007-11-27 Thread Milan
Stephan: Please, I agree CSS is bad, I know this is not Ubuntu nor
GStreamer's fault, though we have to make it as clear and easy as
possible. 1) People always must be made aware of the problems going on -
they surely don't know about encrypted DVDs (anyway Windows is working
where we aren't here) 2) Some may want to install it, and once a
tutorial page explains clearly the legal blur around that (we're not
even sure it is illegal), it should be easy to do that without geek
knowledge.

So totem is the place to add a dialog explaining that each time a CSS
DVD is inserted (assuming GStreamer already tells totem that the problem
is decrypt plugin missing).

[Bug 157099] Re: Automatic installation of DVD CSS support

2007-11-26 Thread Martin Owens
The problem is not Copyright, libdvdcss is GPL software and as such is
completely FOSS. The problem is that the DCMA and EUCD may or may not
put people who distribute this software at risk of criminal prosecution
and up to to 10 years in jail if convicted. Not many people want to
stick their neck out that far.

But there is still a lot of uncertainty since the DCMA has clauses for
compatibility; I have asked the Freedom Law Centre for clarification, I
got bounced how ever because they want the libdvdcss developers or
Canonical to be involved directly.

It may be worth getting the libdvdcss developers involved and asking
them to send a letter to the FLC.

[Bug 157099] Re: Automatic installation of DVD CSS support

2007-11-26 Thread Conrad Knauer
How about this; libdvdcss2 does not exist in the Ubuntu repositories, so
if a user tries to play an encrypted disk in a vanilla Ubuntu install,
there should be an error something like this:

---
Ubuntu cannot automatically install the package required to play encrypted DVDs.

Unfortunately, while libdvdcss2 is software libre, it is not in the official 
software repositories for legal reasons: it may potentially violate 
anti-decryption laws in some countries (e.g. the DMCA in the United States).  
To enable decrypted DVD playback if it is legal to do so in your location, 
please either manually install it or add a repository containing it and try to 
play the disk again.
---

Now, if a user has already installed libdvdcss2 or added a repository
like medibuntu, the user has made a conscious choice to do so and Ubuntu
should accept that and just play the disk/install libdvdcss2 and just
play the disk :)
