I tried enabling DVD playback via the instructions given here:
http://trisquel.info/en/wiki/enable-dvd-playback

I got some errors and I have no idea what is causing them or how to fix them. Any ideas?

Looks like that medibuntu domain has expired. Just download the source and compile it yourself. The package contains instructions. http://download.videolan.org/pub/libdvdcss/last/

EDIT: somebody should file a bug as well

I got an error when trying to configure it. Any idea how I can fix that?

Have you successfully compiled other things? Do you have build-essential installed?

The description of "build-essential" starts with:
If you do not plan to build Debian packages, you don't need this package.

I would bet on the headers of a basic library missing. Is "libc6-dev" installed?

Think of it as a meta package. Its dependencies include libc6-dev too.

Sure, installing it wastes 40kB of disk space but I think most people can live with that. ;)

I don't know why people insist on using descriptions like this. If you intend to install software you will probably need this eventually. In fact, I'm pretty sure I've never not needed to install this (or its equivalent).

That is not true. I have never installed this package, in spite of developing in C++. I installed g++ and make. Why would I need dpkg-dev (in dependency of build-essential)? I do not make DEB packages.

I don't know if I've successfully compiled other things. I don't know anything about installing. I always use Synaptic Package Manager.

I don't have build-essential. Should I install it?

You need it or at least the packages it depends on if you plan on compiling things.

Or follow the updated instructions on the wiki.

That's not necessarily true. You need gcc to compile C programs, g++ to compile C++ programs, probably make, and libc6-dev. Any given program is also going to need other dependencies; one that's become quite common is cmake.

But for other languages, the requirements can be completely different. Python doesn't need any of these, for example.

build-essential isn't supposed to be something you need to compile things. It's defined as "a minimal set of packages that are always needed to compile, link and put in a Debian package a standard "Hello World!" program written in C or C++",[1] and its purpose is to reduce the number of build-time dependencies that have to be listed by packages.

Sure but c and c++ tend to be fairly ubiquitous. According to this [1] ~70% of the packages in Debian 5.0 are c and c++.

I tried following the updated instructions on the wiki and when I got to the "apt-get install libdvdcss" part I got this error.

Oh, it's actually supposed to be libdvdcss2. I've updated the wiki.

This is also a security issue, since the script doesn't do signature checking and someone could host malicious .debs. The script should be removed, and people should be directed to the (updated by jxself) instructions on the wiki page.

I have updated the wiki with information about how to use the apt repo provided by the folks at videolan.org.
