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.

Not a fan of your choice of words, but yes. I do like the idea of storing HD movies on a server and streaming them about the house. So long as they continue to drag their feet with the fair-use copy scheme, I guess methods like this will be necessary.

I don't think there is anything else that anyone could have said that would have done a better job at describing the situation that just simply saying "raped". Well done OP.

I couldn't agree more. I purposely built my file server and coupled it with XBMC for this purpose. (Ya I know the original won't play HD) With a 5 and 2 year old running around I don't have to worry about the disc I buy. They are opened long enough to be ripped and then put away. When the time comes for all HD content and the 360 finally get owned all the better.

Microsoft will be happy again, now you can do more than just watch Blu-ray with your PC. You can 'back-it-up', stream it, soon even modify it...

What does the 360 have to do with BD getting cracked? You lost me there.

I think he's saying that right now he's still using his original XBOX Media Center (?) for playing ripped SD movies since he's still not on HD. Once he moves to HD, that's when he'll get a 360.

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).

Also not a fan of that choice of word. Still it had to happen sooner or later and I'm glad that it has. Kudos to Slysoft.

It makes me happy inside when I see Hollywoods protection schemes fail. They should do like some game companies. Make there games ( in Hollywoods case movies ) incredibly large and not worth it to pirate. I know I wouldn't want to waste my time download 5+GB movies.

Do you watch your downloads from 0-100%? If not, and you're not using all your bandwith, you're not wasting time.

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.

Quoted from AnyDVD HD 6.4.0.0 changelog

New (Blu-ray): Removes the BD+ protection from Blu-ray discs!

Century Fox :-) )


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.
