You might want to experiment with the different cracking methods in 
libdvdcss.
For this you'll have to start VLC from a dos command line after having set 
the proper environment variable (set foo=bar in the dos prompt).

Here is a list of the available environment variables (from libdvdcss's 
README file):

  DVDCSS_METHOD={title|disc|key}: method for key decryption
    title: decrypted title key is guessed from the encrypted sectors of
           the stream. Thus it should work with a file as well as the
           DVD device. But it sometimes takes much time to decrypt a title
           key and may even fail. With this method, the key is only checked
           at the beginning of each title, so it won't work if the key
           changes in the middle of a title.
    disc: the disc key is first cracked ; then all title keys can be
           decrypted instantly, which allows us to check them often,
    key: the same as "disc" if you don't have a file with player keys at
           compilation time. If you do, the decryption of the disc key
           will be faster with this method. It is the one that was used by
           libcss.
           This is the default method,
  DVDCSS_VERBOSE={0|1|2}: libdvdcss verbosity
    0: no error messages, no debug messages,
    1: only error messages (this is the default)
    2: error and debug messages

Hope this helps,
