Yes, Theora is based on the (patented) VP3 codec from On2, but quoting from http://theora.org/theorafaq.html: "Q. Isn't VP3 a patented technology? Yes, some portions of the VP3 codec are covered by patents. However, the Xiph.org Foundation has negotiated an irrevocable free license to the VP3 codec for any purpose imaginable on behalf of the public. It is legal to use VP3 in any way you see fit (unless, of course, you're doing something illegal with it in your particular jurisdiction). You are free to download VP3, use it free of charge, implement it in a for-sale product, implement it in a free product, make changes to the source and distribute those changes, or print the source code out and wallpaper your spare room with it. For more information, check the VP3 Legal Terms on the SVN page." I guess you'd need to speak to a lawyer to see whether that means you are actually immune to being whacked with the patent stick, but it would appear that On2 have indeed irrevocably released the rights to the VP3 patents. I think "patent-free" is better interpreted as "with free-to-use patents". HTH -Taiyo ___________________________________________________________ All new Yahoo!
