Please. Read the dox! There are two totally different DVD support "layer"
inside MPlayer, and you shouldn't mix them! One is the "new-style" DVD
support, eg:

-dvd 2 (only directly from DVD disk)

MPlayer will issue authentication, title/disc key cracking etc, you shouldn't
use ANY -dvdkey option!

While, old-style DVD support requires mounted DVD disk (with new-style support,
you don't need this), and you must specify the exact VOB you want to play/
encode. For old-style support, you must use -dvdauth /dev/dvd (or whatever).
-dvdkey is ONLY for advanced users who want to play/encode a VOB file backuped
from a DVD to his harddisk before (for example).

I don't understand why would you like to copy VOBs first, then encode. You
can do it in one step.

0123456789 is the correct key? It's format is OK, but it seemed to be an
example key only ;-)

Quotes are only for shell, they're nothing for the program.
