No it doesn't, but it does include a shell script to download it if
you're living somewhere where libdvdcss is ok, and libdvdread will
dynamically load libdvdcss if it exists. I'm using libdvdcss 1.2.8 (latest).

Had to reinstall OS X to test this, and yup, it wants a zone to be set.
Returning back to Linux, some fiddling with regionset and some region 1
and 2 DVDs lets me come to the following conclusions:
1) It's an RPC-2 DVD drive (i.e. evil, CSS-in-hardware drive), with the
whole "5 changes and then it locks" policy.
2) It appears to be a really evil variant of RPC-2, in that if you've
got a CSS-locked DVD in the drive, and you're set on a different region
to the disk, you can't even get at the encrypted contents. The
aforementioned read errors keep turning up, making libdvdcss useless.
Or, this may just be an ide-cd bug with this drive...
3) If drive region == disc region, it plays DVDs fine.
>>hdparm -i says the drive is a "MATSHITACD-RW CW-8124".
If anyone happens to have an RPC-1 firmware for this drive, or fixes to
ide-cd, I'd be most grateful! Some googling for the former is currently
