>I guess if you can play it without having libdvdcss installed there's no
css.
I never knowingly installed libdvdcss. I searched in Synaptic for the
libdvdcss package, but there is no package called libdvdcss in the repos.
There is a package called libdvdread4.
The package info of libdvdread4 says
>libdvdread probes for libdvdcss at runtime and if found, will use it to
decrypt sections of the DVD as necessary. libdvdcss needs to be installed
from
third-party repositories (see README.Debian), it's not included in Debian.

>I heard that some countries made it illegal to decrypt css dvds, even though
it's the only way to watch those dvds without proprietary software. Does
anyone know which countries have this rule?
The DMCA (Digital Millennium Copyright Act) in the US makes it illegal to
circumvent DRM, including DVDs.
Here is an article by RMS about libdvdcss's legality in France.
