This is a bit off-topic, but I feel compelled to note that software to
"crack" the DVD encoding was released in 1999 by a 15-year old Norwegian
named Jon Johansen. The original and many other implementations are
still widely available, although usually not in a particularly "user
friendly" form, for legal reasons. Dave Touretzky maintains a "gallery"
of examples at:
http://www.cs.cmu.edu/~dst/DeCSS/Gallery/index.html
and some further information at:
http://www.cs.cmu.edu/~dst/DeCSS/index.html
that together provide a fascinating case study of the both the necessity
and the ongoing difficulty of redefining such basic notions as
"property" and "speech" some 60 years after the dawn of the information age.
I agree with Brian: do not record your original data to DVD.
