I'd like to back up the files on my DVD-Audio discs. The files are

guessing it's because of the encryption. Does anyone know of a method
that would back these discs up in their encrypted form?
That doesn't work that way. What you get is actually garbage and is not
"encrypted" (otherwise you would be able to copy it to another DVD).
Creating a copy of an audio DVD which is itself encrypted would defeat
the purpose of a copy protection, since even though encrypted, it's
still a copy, and the protection wants to prevent that. If you can copy
it, it wouldn't be protected :P
There is no copy protection on a DVD. There is however a region specific
_usage_ "protection".
DVD-Audio works different, utilizing other forms of protection unrelated
to video DVDs. See http://en.wikipedia.org/wiki/DVD-Audio
