Sounds like it.

I suspect k3b does a bit for bit copy, and the VOB (video object)
files are still encrypted. I think you are asking if since you were
able to get .VOB files onto your hard-drive have you bypassed the
encryption. From your descriptions, I'd say in this case no, it
sounds like you now have encrypted .VOB files on your drive.

In a nutshell, IFO/BUP files contain
menu/navigational/subtitle/control/etc information.

How large was the iso? Professionally pressed DVDs are usually
dual-layered DVD-9 (7.95 GB). You probably burned a DVD-R that is in
the single-layered DVD-5 format (4.37 GB). If you are trying to
backup a DVD-5 to a DVD-5, then a bit-for-bit copy should work fine.

Well Bob, http://kavlon.org/index.php/dvdbackup is a nice and current
step-by-step guide for linux. There's more than one way to do it, and
other tools for the job, but this guide seems to cover everything it
sounds like you need and will at least serve as a good method for your
first try. If you want to get a better understanding of things in
general, I'd recommend http://www.doom9.org/ which is Windows oriented
but has good introductions and guides and will probably help in an
indirect way.
