Question 1: “Is it illegal to play back DVD discs I have purchased with the help of Libdvdcss on my Windows 10? Why did I always get unhelpful caution like ‘using libdvdcss to copy legally-purchased DVDs may be illegal in your country’ or some such? How can I know whether or not it’s legal to use Libdvdcss upon DVD discs I have purchased for personal use? Please help me with this.”

Question 2: “I'm a Linux user so in order to play back DVDs on my PC I require the use of 'libdvdcss'. I was wondering as to the legality of this in the UK, I am aware that the law was changed a couple of years ago to exempt the process of ripping content for personal use as a form of fair use (this same fair use right applies in the US as far as I am aware) In the US however using libdvdcss is technically illegal whether enforced or not, this seems clear but what doesn't seem clear is the legal status of this in the UK. I have read in various places that in most of Europe use of libdvdcss is legal as a result of competition laws but I am unaware as to whether this covers the UK so I was wondering if anyone can shed any light on this.”

For DVD movie fans, libdvdcss must be a familiar thing since it’s usually used as an assistance for people to play back and even rip DVD discs purchased online. However, there are regions and countries that regular using libdvdcss is illegal. How can we know whether it’s legal to use libdvdcss or not in our country? Well, in this guide, we would like to make some introduction to libdvdcss and its usage.

Part 1: What is Libdvdcss? Is Libdvdcss legal?

What is Libdvdcss?

First, what is libdvdcss? Libdvdcss (or libdvdcss2 in some repositories) is a free and open-source software library for accessing and unscrambling DVDs encrypted with the Content Scramble System (CSS). Libdvdcss is part of the VideoLAN project and is used by VLC media player and other DVD player software packages, such as Ogle, xine-based players, and MPlayer to play back CSS-DVD discs, even though you don’t own the DVD discs. Also, libdvdcss helps HandBrake and other DVD decoder and encoder tools that have no disc decryption to help you rip and convert CSS-DVD discs of your own.

Is Libdvdcss legal?

Then, the question comes out: is it legal to use libdvdcss for playing back copy-protected DVD discs or ripping copy-protected DVD discs? Actually, this depends on the local law. In some countries like USA, the Digital Millennium Copyright Act (DMCA) makes unlocking cell phones, ripping DVDs, removing eBook DRM, and jailbreaking tablets illegal. And, there’s another surprise regulation: simply watching a DVD on Linux is also illegal. Therefore, if you are using libdvdcss on your Linux computer in the US, you might be considered as criminal for breaking copy-right protection regulations under the Digital Millennium Copyright Act (DMCA).

However, there are also countries and regions that make it legal for you to use libdvdcss for playing or ripping DVD discs as long as you have purchased and owned the copy-protected DVD discs for personal use only like the UK. Therefore, whether it is illegal to use libdvdcss on your computer highly depends on the local laws and regulations. Therefore, you need to consult the local law before you try to use libdvdcss on your computer for playing or ripping DVD discs on your computer.
