small tip - How to play protected CD/DVD on Arch LinuxFollow @ggarron
If you want to play protected CDs or DVDs on Arch Linux or any other distro, you may need to install
libdvdcss, in order to avoid the message "Media stream scrambled/encrypted".
In Arch just enter this at the prompt.
sudo pacman -S libdvdcss
You may also need to install libdvdread libdvdnav, so enter at the shell prompt
sudo pacman -S libdvdread libdvdnav
Now you should be able to play those protected CDs, be sure to have legal copy of any copyrighted material.
