HowTo: Deal with BD+ copy protection when ripping Blu-ray titles using Ubuntu
A fair while back now, I wrote an article detailing how to decode Blu-ray titles using Ubuntu and an LG GGC-H20L Blu-ray optical drive.
This article detailed how to decrypt just about every movie under the sun except for a newer type of protection called “BD+” which I never got around to supplementing my original article with.
What is “BD+” protection? Well in short, it’s the deliberate corruption of random parts of the video track of the movie (well, OK – that is a highly simplified definition as BD+ protection can do a lot more than that, but the end result is the same – to prevent unauthorised playback which includes ripping). The idea BD+ is that when you rip the title, you can still watch the movie, but with some or all of the screen corrupt at various stages in the movie which well and truely ruins the movie-watching experience, especially since you paid good money for it and should not be forced to buy a dedicated consumer Blu-ray player when you’ve got a perfectly good PC that can do the same task.
But hang on, if the movie is deliberately corrupt, then how come it plays fine in a stand-alone consumer Blu-ray player or PlayStation3 console?
Well, let me tell you about that and how to get around it yourself.
HowTo: Rip a Blu-ray movie using an LG GGC-H20L Blu-ray drive with Ubuntu
The Blu-ray disc format has brought with it the ability to easily provide the next generation of High-Definition 1080p movie content. There’s just one problem – Ubuntu and Linux in general has no official support for Blu-ray, and its encryption scheme is vastly different to that of DVD – it’s not just a simple case of installing a library like the libdvdcss2 library for decrypting DVD’s – the protection is done both at a software and hardware level.
This article discusses how I used my recently purchased LG GGC-H20L Blu-ray ROM drive to successfully read and watch movies using Ubuntu Intrepid.
Mini-review: LG GGC-H20L Super Multi Blue Blu-ray Disc & HD DVD-ROM Drive on Ubuntu
Optical storage certainly has come a long way, and with each new advance brings new affordable hardware to help nudge it along. The HD-DVD and Blu-ray disc formats brought along with it the ability to store and distribute high-quality, full high-definition 1080p movies.
Unlike when DVD first appeared, and probably thanks to the battle that was waged between the HD-DVD and Blu-ray formats, the provision of high-definition media and associated players has dropped in price rather dramatically to drive acceptance. I have a fairly large original DVD collection, but I am a quality freak and in light of high-definition releases, I loathed the idea of buying a DVD version of a given movie knowing that for about the same price I can buy a high-definition version.
So I decided to buy a Blu-ray drive. One of the cheapest options on the market is LG’s internal drive option called the “Super Multi Blue Blu-ray Disc & HD DVD-ROM Drive”, model GGC-H20L for about AUD$150. This review is my experience using the drive under Ubuntu 8.10, Intrepid Ibex.
