Latest Blu-ray Disc copy protection circumvented by PC software

Although Hollywood movie studios have little choice in which format they release their high-definition content, companies such as Disney and Fox chose Blu-ray Disc for its added copy protection features.

Since the AACS copy protection scheme was defeated, Blu-ray Disc had BD Plus (BD+), launched in June 2007 as a secondary protection method.

Like any other software protection scheme, however, it was only a matter of time before BD+ would be circumvented. In the latest version of SlySoft AnyDVD HD, released on Wednesday, the top new feature notes that the 6.4.0.0 software can now remove the BD protection from Blu-ray Discs. The release note also mentions that the removal of BD+ increases compatibility with titles released by Twentieth Century Fox.

Effectively an embedded virtual machine inside player hardware, BD+ allows content providers to include executables on Blu-ray Discs to perform specific, content protecting functions. For example, the BD+ virtual machine could run diagnostics on the host environment to see if the disc player has been modified, or to verify that the keys have not been changed.

As part of the BD+ scheme, video may be deliberately corrupted or modified to prevent the ripping of the data stream for piracy purposes. The BD+ environment, once verified, will correct and descramble the content to render it viewable.

I thought the entire purpose for movie studios to move from DVD and one of the main reasons why BD had more support from major studios at first than HD-DVD was because of this additional copy protection scheme.

When will these Holywood suit ever learn. Try as you may, your DRM schemes will never prevail. Stop wasting your money on it, it only causes more headaches for those who want legally archive their media and does absolutely nothing to stop copyright infringement.

I believe the point is you have a BD player in your computer and you can decode and export the stream. You know, copy it. It's not like they're talking about altering the bios of the player, they're talking about bypassing the security so a computer can decode it.

And hes saying, when you put in a new store bought BD which contains new updated keys into your standalone BD player, the cracked keys will no longer work. Not sure if this is true, but i think i remember hearing something similar.

What good is a BD if you can only play it from a computer, most people don't have HDMI out, and it is very hard to set up lossless sound.

computer players are no different than stand-alone players.

maybe you can rip the stream and convert it to DIVX or something, but only at a loss of quality.

of course that's probably what the bittorrents will do anyway.

So you transcode the movie so there's 0 remnants of the original encryption - Sony are going to find out the cracked keys... how?

To put it another way, I pick up a car with various ID numbers on the chassis. I'm going to 'clone' this car, so in the process I put new plates on it, and sand off all the ID numbers. How is the original manufacturer (or anyone for that matter) going to know what the numbers were?

AnyDVD removes all traces of copy protection from the disc so the player has no "keys" to even bother with at all.

You are think of Media Key Blocking which is designed to revoke compromised player keys. For example, PC software players, such as PowerDVD and WinDVD, were first utilized to crack AACS. Shortly afterwards, movies released with a new MKB table revoking the keys of the compromised players.

While BD+ will most certainly change over time. DVD copy protection still changes and Slysoft is all over the updates on a regular basis so I have no doubt that anything the studios do will be futile.

If you keep the price of the blank media near the cost of the movie, it isn't cost effective to copy.

1 blank $15
1 hour to rip and burn (guestimate)
1 Sheet of photo paper for the cover + ink
1 clam shell
time searching for, or scanning, or creating cover art.

Personally, my time(that it takes to copy)is worth more than the cost of the $25 movie.

as always, your mileage may vary.

For many of us, this isn't about piracy, it's about re-encoding movies for our portable devices, streaming it to other devices in our house or backup to storage array. It's about letting me play movies I paid for on devices without HDCP encryption and a Blu-ray drive.

Most pirates don't care about HD yet anyway. The 'pirates' I know watch movies compressed far below DVD quality and couldn't care less. It's just some strange obsession with collecting movies for free.

Sure it is.

Those making the copy protection know that it will not work forever the real point is to make copying impossible for the average Joe. Sure us geeks will find a way but it will take some time for the tools to be wide spread meaning the copy protection will work fine for the majority of the products sold.

It is the same thing with for example copy protected PC games. You and I know how to make a disc image and download a No-CD crack in minutes. But the less computer savvy do not so they are not able to make a copy and/or pass on the game while still being able play on their own system.

Of course eventually even the average Joe catches on and find out how to get copies of whatever but even then it still leaves Joe Stupid to "benefit" from the copy protection.

Therefore the copy protection is successful.

That is just faulty logic to me. I agree that protection is used to keep the average joe from copying it. Hell, even now most people don't copy DVDs even though it is INSANELY EASY. The problem with using that argument for newer protections is that if the average joe can't copy the old discs with the old protection, why implement a new protection. That's just stupid. Of course, without knowing how much they spend on researching new copy protection schemes it's impossible to say, though I think we can safely say it's not going to be less than $1000.

You've gotten to the heart of the matter. Bandwidth.

Having cracked BD+ and "liberated" the bits, it will be tough to share a 30-50GB image (for the time being - but perhaps easier in 5+ years).

Most likely, the image will be transcoded to something like DivX HD, which is a more efficient HD encode, so allows sharing of a smaller file.

There will be a trade-off between having a portable DivX HD and the real thing with uncompressed audio and video streams.

So this liberation and transcoding means that there will still be sharing and trading of these unlocked movies, but they will not be true HD quality.

The same thing happens today, the Torrent sites have DVD "rips" which are seldom the whole 8GB DVD, typically transcoded down to 4GB, 1.4GB, and 800MB sizes. This liberates the locked content from a DVD, but this is "good enough" for most average Joes.


RE: Why bother
By rninneman on 3/21/2008 9:31:31 AM , Rating: 4
Divx HD is MPEG4 just like most Blu-ray discs. All a lower bitrate is going to do is reduce image quality which kind of defeats the purpose of watching it in HD. The reason why DVDs can be shrunk so much is because the difference between the efficiency of MPEG2 and MPEG4 is significant.

You can convert a BD rip or HD-DVD rip into H.264 in a Matroska container. That's how people share BD rips now. No one shares BD images. I do see some DivX HD, but H.264 Matroska files are much more common.

Your average 1080p film is 8-11GB, but I can still download most of them on my Comcrap connection in under three hours. I'm not aware of any real quality loss in the ripping or converting procedures, though I'd imagine there is some. But 9GB or so is very reasonable if you've got a 6-10mb cable connection to saturate.

that's assuming that the whole movie takes up 30-50gb. it does not. once you rip out the special features, menus, and extra audio tracks it is much smaller. Around 10-15gb for just the movie.

By gramboh on 3/24/2008 2:06:46 PM , Rating: 2
The way the HD 'scene' works now is private torrent trackers where both the original untouched Blu-ray/HD-DVD image is uploaded (20-35GB usually) as well as x264 encodes in the .MKV container. As said above, for 720p (with DD 5.1) these are roughly 4-5GB (fit on a single DVD) and for 1080p with DTS 5.1 audio they are 8-12gb depending on the length of the movie. People also encode to WMV-HD for streaming via the Xbox 360.

On one hand, the userbase doing this is relatively small and sophisticated due to the bandwidth and HDD space requirements, so Hollywood probably isn't too concerned versus DVD piracy, but on the other hand, they are probably upset it is happening so easily/quickly with HD content.


Still a game of cat and mouse...
By Aaron M on 3/20/2008 11:06:22 PM , Rating: 4
From the press release at http://forum.slysoft.com/showthread.php?t=14786:

We are rather proud to have brought back to earth the highly-praised and previously "unbreakable" BD+. However, we must also admit that the Blu-ray titles released up to now have not fully exploited the possibilities of BD+. Future releases will undoubtedly have a modified and more polished BD+ protection, but we are well prepared for this and await the coming developments rather relaxed".

Looks like, unlike with DVD, BD+ will be a moving target, forcing Slysoft to continually create hacks around newer movies. Like someone said, earlier, BD+ was created with the assumption that it would eventually be cracked.

I guess, one could see this as a compromise for movie studios and consumers. I see it like this: A movie comes out with updated protection. Now Slysoft needs to work on a new hack for it. Well, that gives Blu-ray timed-exclusivity, the period in which the movie is likely to earn the majority of its sales. The hack comes later, when sales have already tapered-off. I see this as an "as good as it gets" scenario for movie studios, in a world where no copy protection can be assumed to be uncrackable.

Their software is incredibly good. It is updated with a regularity that amazes me. And they give you free updates for life.

As far as moving target goes, even with DVD's this is true. They are constantly releasing new ANYDVD updates to deal with the latest feeble attempt at keeping people from copying DVD's.

AACS is also a rolling DRM technology. The problem with BD+ is that once it is broken, you don't even have to deal with AACS since BD+ has direct access to the unencrypted content.

Seriously, that is what makes me so upset at the MPAA and their goonies. How is it that after I BUY a product, they still basically own it? After I make a purchase, it is up to me to decide what I want to do with that product. No non-government agency should be allowed to dictate what goes on with the product I just purchased legally with my earned money.

I wish Ford would tell me I couldnt give other people a ride in my car because they did not pay for it. God forbid I give someone the keys to my car to drive to the corner store.
I also hope Hanes and Fruit-of-the-Loom don't get in contact with me because my wife wears my clothes to sleep in, clothes that she never paid for.

I understand these are not cases where a 'true copy' was not made, but it has similar principles. These entities do not want other people using or having what they have not paid for, and it just makes it worse when these other people have an actual copy.

Even if you can't crack the BD+ or other schemes, you can capture video at 1080i using a Black Magic Intensity Pro video capture card. It features component and HDMI capture.

To get around it not working with HDMI, I purchased one of the new HDCP strippers for HDMI. These are popping up from Asia, so keep an eye out if you want one. It basically makes the player believe it is connecting to a valid device and the stripper passes the data thru to the HDMI capture card. It is really quite nice.

I give it a year or two before so many of these HDCP strippers are making it into the USA that you'll be able to find them online without worry.

I understand why movie studios and other media companies try to protect "their" property. But considering anything they come up with will be cracked/bypassed etc., why dont they just drop the efforts.
I've always thought that they spend way to much resources on copy protection and such, and that reflects in the final price of their products (movies, music, games and other software.
If they could cut prices by droping this "investment" wouldn't it possibly help to actualy reduce piracy in some amount, I mean copy-protection maybe slows it down for a little while sometimes but at the end "resistance is futile".

Just a thought, what do you guys think?

They could cut prices and sell a lot more dvd's, but their strategy is to maximize their profit and screw anyone in their way (even legitimate buyers)

You see it all the time, people on the streets hawking low quality $5 knock offs. If media companies were selling DVD's for $5 each I doubt you'd see as much piracy as you do today. And they wouldn't need copy protection and they wouldn't screw Joe average DVD owner in the process, and they wouldn't piss everyone off with DRM.

Honestly how much does it cost to produce a DVD? 10 cents? At $20 a DVD that's a lot of money. They're probably seeing the situation in green colored glasses.

Media companies have the right to protect their intellectual property from abuse, but if they played the market right, they wouldn't need to use DRM and cry about illegal copying etc.

You can stream HD content over a network from a server to your entertainment system via the 360. Ripping HD-DVDs and BDs to MPEG-4 or WMV-VC1 files will work this way. You save wear and tear on your discs and have the added convenience of simply selecting your movie by name in a list and pressing "play". Great for kids and a very high WAF (Wife Approval Factor - a necessary component of any home theater).

That isn't even close to being what others feel. Just visit any torrent site and see how many people think it is worth it to download a 5+ or even 8+ GB torrent. Whether its a game or a movie in 720p or 1080p, you'll see people by and large will take whats free.

And to the person wanting lossless -- BluRay isn't lossless. As in, not even close. You could store a very small amount of video in full lossless on a double layer BD-ROM. Just by my quick calculations, I estimate 335 seconds. Yep, full lossless 1080p with no audio, and no menus, and no free bytes left on a 50GB disc will net you about 335 seconds.

BluRay (and HD-DVD for that matter) uses a VLC-1 compression scheme. Turns out that is the same codec as H.264. This is an extremely good codec, albeit a little bit CPU intensive. On average, a full length film will be about 20-30GB with the audio (which isn't lossless, though a disc may have such an option, the standard is Dolby Digital 768kbps or DTS 1536kbps, both in 7.1), without the menu and extras. So, if you have 30GB at 1920x1080, figure you downsample it to 1280x720 -- that should knock out 55% of the space required to maintain the same quality. So, a 13GB 720p file has the same quality as 30GB 1080p file. Clearly, a 20GB 1080p file can fit on a DVD+DL disc when converted to 720p. So, throw in a little more compression from the release group and you can easily fit 1080p on a DVD+DL, and 720p can even be compressed down to DVD+R, though excellent quality can be achieved on DVD+DL. Not to mention the initial 30GB includes foreign language tracks, which are generally discarded.

So, my point is that you are not getting lossless quality from a BluRay disc. And from a compression standpoint, its totally feasible to make a BD video fit into DVD+DL or DVD+R size restrictions without much noticeable video quality loss. Atleast, if we restrict ourselves to consumer products.

BD+ was implemented with the thought of it inevitably being cracked. You'll have to circumvent the BR hardware to get any real use out of this exploit.


Oh really, thou who knows all?

People have already used this to re-encode formally BD+ protected movies into different formats, and have burned the unprotected output to BD-R discs and played them in set-top players and the PS3. BD players will play discs with no content protection, which is exactly what you get after using the new version of AnyDVD HD.

Yes, please show a picture of yourself ripping a BD+ movie. Be sure to include your name and social security number as well (for verification purposes)

I don't want to spend time hunting down public posts, but it's very much real. I'm on a private backup site (i'd link you but it's private) where the users were posting about trying the new AnyDVD with known BD+ movies (ice age, simpsons, live free, I Robot...). it's been agreed upon that it works for most movies. this is not a "huh look at me i did it first" site, this is real discussion. i've seen before and after screenshots of BD+ playback before and after AnyDVD. with BD+, the playback is garbled. they were testing the beta that was accidentally put up on wednesday, the final may work with all BD+ movies. you're right to doubt, but i can tell you that it works, at least for most current movies. i'm sure they'll try to change the BD+ on new discs to stop AnyDVD.

Do you even know what AnyDVD is? The point of AnyDVD is to remove the DRM from the discs so that you may use it as you please. He doesn't need proof because Slysoft said it works. I would tend to believe them based on the history of their products.

It looks like it says removes BD+ to me.

It's already widespread on privte torrent tracker sites, people have ripped and encoded via x264 movies like the new Die Hard, Ice Age etc.

Why does the hardware have to with circumventing BD+? If all traces of DRM are removed from the disc during the ripping process as AnyDVD does, the player thinks it is just a regular unencrypted disc.

Police in Radnor, Pennsylvania, interrogated a suspect by placing a metal colander on his head and connecting it with wires to a photocopy machine. They placed the message "HE'S LYING" in the copier, and pressed the copy button each time they thought the suspect wasn't telling the truth. Believing the "lie detector" was working, the suspect confessed to the police.
