 The behavior of the library can be changed by setting two environment variables:

   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 too 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.

+    disc:  The disc key is cracked first. Afterwards all title keys can be

+           decrypted instantly, which allows checking them often.

+    key:   The same as the "disc" method if you do not have a file with player

+           keys at compile time. If you do, disc key decryption will be faster.

+           This is the default method also employed by libcss.

   DVDCSS_VERBOSE={0|1|2}: libdvdcss verbosity

     0: no error messages, no debug messages (this is the default)

     1: only error messages
