[MPlayer-dev-eng] -dvdkey option obscurities

[Diego Biurrun]

Hi!

While reviewing cd-dvd.html I stumbled across

  -dvdkey <CSS key>
         (old-style DVD option) When decoding from  non-DVD,
         this  option  gives the CSS key needed to crack the
         DVD (the key is printed  when  authenticating  with
         DVD).

Which I found extremely confusing..  I guess non-DVD means a VOB
copied to disk, right?  Or can it be something else?

This is what I would make of it at the moment:

  -dvdkey <CSS key>
      (old-style DVD option) When decoding a VOB, this option gives
      the CSS key needed to crack the VOB (the key is printed when
      authenticating with the DVD).

Is this complete and correct?  Please somebody enlighten me, so I can
update the docs.
Thanks

Diego

P.S.: This may seem really simple and obvious, but I do not have a
DVD, sorry.
