What is CSS on a DVD exactly? What does it do technically?

Content Scramble System -- its the "copy protection" on a DVD.

More info at their site.

Of course, a teenager in Finland (or somewhere) cracked it so he could play DVDs on his Linux system, and now it's just about useless... at least until Blu-Ray comes along...

I want to make back-up copies of my disks (some of which have CSS on them) via computer, so do you have any idea of how to get around it, or is that a naughty question?

Yeah I would edit your post. Don't worry it gets asked a lot but the first question is great. The second post needs to be deleted/naughty.

Maybe a sticky with that rule is needed.

"Cracked it" is giving the kid too much credit. Some Korean DVD-ROM drive didn't properly protect the decryption key as per the CSS License Agreement. After someone found the decryption key, the kid was able to reverse engineer CSS and create the DeCSS program.

If it weren't for the improper handling of the Decryption key, CSS would likely be just as strong a copy-protection methodology as it was when DVD was first introduced.


And yes Mojo, your question is one that is not appropriate at ADT. As such, I am closing this thread.
