Blu-ray BD+ Cracked

An anonymous reader writes "In July 2007, Richard Doherty of the Envisioneering Group (BD+ Standards Board) declared: 'BD+, unlike AACS which suffered a partial hack last year, won't likely be breached for 10 years.' Only eight months have passed since that bold statement, and Slysoft has done it again. According to the press release, the latest version of their flagship product AnyDVD HD can automatically remove BD+ protection and allows you to back-up any Blu-ray title on the market."

      Absolutely. There is one caveat, however: Do you think your 4head VHS recorded copy of a BlueRay disk is going to look all that good?

      Even if you record in another digital format you're going to lose quality and at the same time run into possible signal loss problems (depending on your setup) while the picture is on the wire.

      I'm no expert, but I have done some TV capture and video encoding stuff with VirtualDub and if I were going to do this, I would want to use some kind of digital signal out (HDMI, DVI) of one computer DIRECTLY into a digital video input of another and capture all the images in some kind of raw format (I'd want to do similar with the audio). Now, keep in mind that you're losing a lot of resolution that's available on the disk that your graphics card likely isn't capable of spitting out, so, if you're lucky, the result would look almost as good as the original disk and, assuming it is, the resulting file would be HUGE (like, I-don't-know-if-NTFS-can-handle-that-big-of-a-file kind of huge). This is all assuming that you didn't get IM'd or have a system tray balloon pop up while you're in the middle of this process.

      Technical details aside, there's still one practical problem: You'd have to play the movie at normal speed to record it to another format/device anyway, so you might as well just watch it where you're at and forget about trying to capture it.

    Slysoft has made this claim before. It turned out to be bogus. The crack allowed a user to copy a BD to the harddrive and play it back from there using only a specific version of Cyberlink's PowerDVD (3319a), but not to transcode, otherwise manipulate the content or play it back from a burned BD-R or BD-RE. (Wiki)

    Now I'd like everyone to remember that BD+ is not an `algorithm` per se. It's not a DRM one way function. BD+ is a virtual machine and a blu ray disk is a full fledged program that runs under the VM and can even run native code to patch and upgrade the virtual machine.

    This is akin to running a java application that can inspect the java VM.

    It's a cat and mouse game for now.

    It's OK to make bold statements if you can do it with humor and not depend on the failure of that statement.

    But when it comes to things like DRM and security it's just a disaster waiting to happen. What happens is that this will be a magnet and a challenge for all hackers regardless of intent just because they want to prove the statement wrong.

    The crack allows you to play the media at full quality on systems that do not have a fully HDCP compliant chain.

    You bought a disk full of data.

    DRM locks the data to the disk, requiring you to risk damaging the only copy of the data you bought in order to access said data.

    Fair use is copying the data you bought to another device so you can access it from there.

    I'm surprised you need it explaining to you, are you a bit dumb ?

    The copy protection is meant to prevent you from backing up your only copy of the disk to another device, which falls under fair use. Also, you cannot format-shift because of the copy protection. If you buy an HD movie and want to downsample it for use on your iPod, you can't unless you get past the copy protection.

    The studio's line works just fine if you're okay only watching your movies in your Blu-Ray player and only if the keys to the disks are still valid and only if you even still have a blu-ray player years from now. If you buy a movie you should be able to enjoy it howsoever you see fit as long as that doesn't involve charging people money to view it or selling copies you've made from it.

    Dump all the pixelvalues as arrays into a screenshot bypassing Windows, then stream together the screenshots in a video format of your choice, and you've got uncompressed, perfect digital video.

    No, you don't. It's uncompressed, but not "perfect" because it still has the compression artifacts. Then, when you recompress it, it has two sets of compression artifacts. Although it's higher quality than aiming a video camera at the display, it's still more-or-less the same as the "analog hole."

    To really count as "cracking," the attacker needs to get access to the decrypted but still encoded stream.

    The different Blu-Ray "profiles" require different hardware, which is obviously not something that can be fixed by a firmware upgrade.

    Profile 1.0, otherwise known as the grace period profile, only required 64KB of local storage for key revocation lists.

    Profile 1.1, which is the "final standard" profile (though it was only required for players released after 11/1/2007, leaving over a year of BD player production supporting an incomplete featureset) requires 256MB of local storage as well as secondary audio and video decoders to allow for PIP and overlay audio commentary.

    Profile 2.0 adds networking and Internet connectivity to the mix and ups the local storage requirement to 1GB. This profile is equivalent to the features that have been mandatory in HD-DVD from day one.

    The only upgradable hardware BD player is the PS3, since it already had the hardware for other purposes. Profile 1.1 support was pushed out in a software update soon after it became mandatory in standalone players and profile 2.0 support was announced yesterday and is expected some time next month.

    There are a variety of reasons HD DVD was better from an end-consumer's standpoint, though not necessarily a studio's:

    1. It was more affordable
    2. It supported combo disks, meaning people buying movies could buy them safely in the knowledge they didn't have to upgrade every player in the house to HD DVD in order to play it
    3. It supported non-encrypted discs, meaning smaller studios had access to the format without the need to pay AACS fees that would significantly increase the cost of the media, and also meaning free content was possible
    4. It had everything two years ago that Blu-ray's BD Live and Profile 1.1 supports (but few Blu-ray players are capable of.) An HD A1 can do all the PIP, etc, features that are being announced today for future BD players
    5. For encrypted discs, "managed copy" was a compulsory feature, allowing manufacturers to produce movie jukeboxes, systems to copy movies to hand held devices, etc, safely in the knowledge that no HD DVD disk could ever be pressed that wouldn't be able to be a part of such a system
    6. There was one copy prevention system, AACS, which was a known quality and relatively uncomplicated. BD+ is a nightmare, several legitimate players have difficulty with it.

    The only real downside was the lower capacity, and with an HD DVD disk topping out at 30G (there had been a plan to increase that to 50G without increasing the price of the players by adding a third layer), capacity for an ordinary 1080p movie was never really an issue. I hear they had trouble fitting a lossless soundtrack on the Transformers HD DVD, one of the rare occasions the capacity was stretched, and there's some evidence that wasn't true either. My 2001 HD DVD has gorgeous quality, a DolbyHD lossless soundtrack, and a whole bunch of features, all on one single sided double layer disc.

    You don't understand how Law is supposed to work. _People_ create Laws, and created Government to work/serve the best interests of everyone, not the other way around. Law is not some "absolute" codified rule -- thats why we have the Spirit of the Law (Theory), and the Letter of the Law (Application). When the Law no longer works, we have things such as civil disobediance. Copyright is an archaic hold-over from when publishers didn't want competition. Imaginary Property rights are the next absurd idea that will eventually collapse. i.e. In Canada, copying music is Legal because people understand that there is no difference in loaning your CD to a friend, or giving him a copy.

    Just to be clear, pirates aren't the ones playing that cat and mouse game. When you see a street vendor selling pirated copies of Star Wars, he's selling actual Blu-ray discs. He made bit-for-bit copies and he didn't need to decrypt anything to do it. The fact that Blu-ray is encrypted didn't do anything to prevent the pirate from stealing the content.

    Decryption is needed by people who want to *gasp* watch the discs they legally purchased at BestBuy.

    Ah, your post takes me back to when DVDs were first being ripped. The same arguments of impracticality were being made then. "DVDs hold 8 gigs, and we only have ~40 gigs of HDD space to store the VOBs."

    There's a difference now, though. Back then, you had to recode the vobs with some crappy (by today's standards) codec like old QuickTime, or asf or something. Nowadays, DVDs can be recoded and stored in XviD format with a decent quality tradeoff. Likewise, BD can be recoded to x.264 and stored in about 4.5 gigs. ...or so I'm told.

    Its also an entropy thing. It may well be that like almost everything else we observe information follows a concentration gradient. That is if you concentrate information with a small group of people you have to constantly expend energy keeping it there. So if you decide gee I only want people who purchase a certain bit of plastic to watch my move you have to put alot of energy into keeping the movie on the plastic. Eventually it will get off if you don't. It may well be that DRM is like heating your house; the more insulation you have(stronger DRM scheme) the better but as soon as you take the input energy away (turn off the heater)/(complete your encrypting) the temperature will always equalize with the outside(the movie will propagate to places where the disk is not present).
