Vorbis is an audio codec, Theora is a video codec. Ogg is the transport layer that both are stored in, so a video file will be Theora-encoded data inside an Ogg file, while audio is normally Vorbis-encoded data inside an ogg file.

The BBC claimed: > There is no open source digital right managment All I have to do to prove this false, is to demonstrate that 1 Open Source DRM solution exists. You must therefore disprove that all the following exist: http://www.sidespace.com/products/medias/ "Media-S is an open-source development project that aims to create an open Digital Rights interface for the creation, playback, and management of multimedia files. Because of its open nature, Ogg Vorbis will be the first format to be protected by this initiative." Og Vorbis is an audio format, isn't it? So that's no good. And the project "aims to". Now, I'm not spending my afternoon looking through code but that imples it's not finished / ready yet. Everything's in future tense. So we can discount that. https://dream.dev.java.net/ Hmm. Looks much the same. A white paper from two years ago, and the declaration that "DReaM is an initiative to develop open Digital Rights Management (DRM) solution for multiple domains". "An initiative to develop...", not "a fully fledged system..." Scratch that then. http://sourceforge.net/projects/openipmp Looks better, but a quick browse of the forums seems to indicate a lot of people (and as it's a project in deveopment, I'm guessing most of these people are pretty clued up on techy matters) are having a lot of problems even getting it to work at all. So that's your three "alternatives" dealt with. Rich. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
