A new optical disk technology offers a fundamental new capability -- which is storing offline archives in a format with a shelf life of many decades (or even centuries). The key is in the pits: unlike commonly available dye-based CD-R and DVD-R media, the Millenniata writer actually laser etches physical pits into the writable layer of its "M-Disc" DVD-ROMs. Because the pits are physical structures, like the pits on pressed media, they have the same kind of shelf-life -- but in a way that is economical for low-copy archives. The niche here is for digital archives of "time capsule" data: family photographs, historical records, original manuscripts, video footage and masters, and so on. Perhaps more remarkably, the drives and disks, are affordable enough for the target applications and available commercially right now.
There are not a lot of free software options for mastering DVDs. One of the more complete solutions is QDVDAuthor, although it still has a number of rough spots. It's a front-end to a collection of command-line free software tools that do each of the individual steps involved in going from a collection of digital video files, audio files, and images to a DVD with menus. As such, it's quite complicated, and not as stable as some software. Still, it is a rewarding experience if you stick with it. Here I'm going to walk through creating a DVD for a collection of animated videos by my new favorite free-culture artist, Nina Paley (partly because the CC By-SA 3.0 license eliminates any questions about copying the material here, and partly because they're pretty cool in themselves).
A DVD that comes with lots of great examples of Free Culture which plays in your DVD player, with even more examples when you put it in your computer – including a GNU/Linux Live CD. The idea is simple: help to get the word out about Free Culture, including Free Software, by showing off what's already been achieved; the thing is, we need your help!
