Where can I get a copy of DeCSS or the source code?
You can find the source code at www.opendvd.org. You can find a copy of DeCSS just about anywhere; since December 1999 a massive mirroring campaign has been underway to distribute it as widely as possible. Try a search engine and search for “decss”; you should be able to find it easily. The Openlaw website currently has links to several major lists of these mirror sites. There are currently anywhere between hundreds and tens of thousands of copies of DeCSS currently posted to Internet web sites worldwide. No one knows exactly what the true numbers are.
