ok i did RTFS...

actually it isn't so simple.

the key getting process has 2 major steps:

1. getting the disc key
2. getting the title key

for both steps, there are "white" and "black" method: ioctl() and crack.
the ioctl method is the default:

1. try to get disc key via ioctl()
   [if this step fails, it will fallback to disc key crack (using 64mb hash),
   this can be also forced by DVDCSS_METHOD=disc]
2. try to get title key via ioctl(), using some player keys included in css.c
   [if this step fails, it will fallback to title key cracking, this can be
   also forced by DVDCSS_METHOD=title]
