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). > Have you tried booting OS X and playing the DVD once ?

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 unhelpful. Thanks, Tom Parker
