One of my daughter's DVDs is garbling and freezing near the end when
played in a STB DVD Player. I have tried to rip it using the most
effective (six nines) tool I've ever seen which is
http://ripitapp.com/ and it gets to 99.1 and hangs. I'd like to try
some form of geeky Linux rescue. I don't know much about what ever it
is that encrypts a DVD, so please be gentle. I'd like copy the disc
with ddrescue, then decrypt that. This thread
http://ask.metafilter.com/68265/But-its-just-a-little-scratch makes it
sound like ddrescue will copy the disc decrypted if it is opened with
libdvdcss first. That sounds like crazy talk and if true means I know
even less about the encryption voodoo than I thought.

Linux users are constantly using machines in unintended ways. What
have you done to salvage (not pirate, I don't even want to know about
that) a DVD?
