Okay, I'm going to veer off-topic for a second:
Cool feature; do you have to do anything to enable it, either at runtime
or compile-time? I ask because I have a Pioneer DVD drive (on a machine
running Mandrake 9.1) that simply wouldn't play DVDs with MPlayer, Ogle,
or Xine until I flashed it region-free.
It may have been that my install of libdvdcss wasn't quite right, or
perhaps an oddity of that drive, but I banged my head against that one
for a few hours before flashing the drive in a fit of desperation, and
damn if it didn't work.
