Cinavia protection is implemented by adding a watermark to the audio track that is then detected by the player which stops playback if it does not match the AACS key on the disc. So far the success in beating this protection was rather small, but now software developer Pixbytes, the authors of programs like DVD neXt COPY and DVD-Ranger, claim to have broken the Cinavia protection that comes on many Blu-Ray discs and DVDs and stops playback of copied discs that were protected with Cinavia on certain Blu-Ray players.
According to the authors, the protection was broken accidentally while developing a different software. While not actually removing Cinavia protection, the signal was changed in a way so that it has become unreadable thus disabling the protection by using a design flaw in Cinavia.
Right now the software is still in development and the authors report a success rate of 55% on the tested Blu-Ray discs and DVDs. The release of DVD Ranger 5 is scheduled for October 31st and will cost $89.99 plus $39.99 for the Cinavia module. Pre-order price is $69.99 – including the Cinavia module.
What do you think? Will their solution actually work and if it does will the industry to find a way to work around this again? Can we expect other software to include this “fix” as well? Anyone has an idea how they may have managed to bypass the protection? Feel free to comment and share your views with us.

That is awesome news and looks like it will lead to a full solution once they've tweaked it.
I wonder if this is completely non-destructive to the audio though?

I think the solution cannot be non-destructive, as even Cinavia itself isn't non-destructive. It has to change (destruct) the audio stream in order to add the watermark. However the question is not whether it is destructive or not, but rather if it is possible to hear the difference between the original soundtrack and the modified one.
Found a nice (old) article on audio watermarks today, perhaps it's worth reading this one.

Yeah that's a good article.
I'd read that before when researching Cinavia and the likelihood of it being defeated.
IIRC the key difference between these challenges and the Cinavia problem is that no untouched versions of the Cinavia infected audio are available for comparison.
Interesting stuff though and TBH some of the mathematics involved is a bit beyond my limits.

Most copy protections work in obscurity.. once people understand how they work, methods can be developed to defeat them. You also can't put it past this nasty blu ray consortium to use "connected" blu ray players to phone home over the internet if they detect "copied" mediums of which the copyrights/watermarks have been tampered with..

I have to admit that I still prefer physical discs (DVD or Blu-Ray) over mpeg, mp4 or mkv files. DVD and Blu-Ray is something you can play on almost every machine, while I've already seen several incompatibilities of other formats on certain devices like MKV file can be played - sound is missing.

Now that Optiarc is leaving the optical drive business, what does the future hold for you? Shift your attention to firmware mods on another brand? Or possibly something more extreme, like a move into console hacking, apple device jail breaking etc?

Or, just keep a pre-2012 player around that has no Cinavia decoding.

I'd rather not be left in the future with a pile of expensive backups that won't play on a newer player, so even though I'm not currently affected, removing Cinavia seems like a pretty good idea to me.

It's also good to note that only a minority of titles have Cinavia protection. Currently only Sony is using it extensively and most studios are avoiding it due to its cost. Warner has released a few. Other studios like Lionsgate are investing in other copy protections. Ultimately the bottom line will drive studios toward or away from Cinavia, so one can always vote with one's wallet.
Cinavia took 10 years to develop but far less time to break.

Also it remains to be seen if new Cinavia variants will appear that beat this currently proposed solution.
It's still a major breakthough though and will hopefully have broken this protection for good.

Freq, it reminds me of King George's stamp tax, meant to raise about $20k. The colonists boycotted British ships and quickly cost the King's coffers about $100k. The Parliament, under the wise advise of merchants, repealed the stamp tax. King G did it again, and the same results, only quicker and steaper losses resulted. Again, the Parliament repealed it. On the third try, the King sent troops into the colonies to force new taxes. This added at least $50k a year to the project, and by 1781, the King had spent several hundred thousand, lost thousands of lives, was ridiculed by the French, Dutch and Spanish, and lost his colonies, too. All for $20k - way to stay focused, Kingie.

Plus if one company managed to break this protection, others should be able to find out how they did it and implement this in their own products.
My guess is that they cannot actually remove the bits inserted by Cinavia, but just add further bits, confusing the Cinavia detection mechanism.

Buying 2 originals won't guarantee loss, of course. And we've seen so many titles go 'out of print' that studios definitely won't guarantee we can buy a future copy.
At least Disney is upfront about this - "On sale for 6 months, then maybe in a few years, this title will return to market." They achieve two goals - one, they force quicker sales and reduced inventory-time, and they reduce inventory space, overall, freeing up shelf space for their next line of titles.
We still have several hundred commercial VHS tapes that were never put on out DVD or, perhaps worse, more edited versions on DVD than the original VHS offerings. But this also occurred with the original LaserDisc offerings - if titles are produced onto future media supplies, consumers have no guarantees of anything. "Do it ourselves" seems to be the best choice.

It may be indeed therefore be impossible to remove but possible to circumvent triggering of its activation routines.
That would be another slight degradation in the audio quality but hopefully it's still unnoticable.
Wombler
The Cinavia "signal" is not audio as we know it. It uses a differential in the S/N ratio to create a small data signal. I forgot the amount but it's measured in bits. It's only applied in the audio during passages with enough sound to mask it. If anyone WAS actually able to hear it - it might sound like a brief pulsing hiss, but it doesn't actually effect the audio quality per se. Questions of audibility or "degradation" aside, it cannot be removed from a bitstream, the audio would have to be decoded then the signal somehow masked. Odds are high that removing it or masking it would be far more audible than the signal is.
It's correct that the real solution will be in the playback device, either a hardware or firmware hack, or perhaps if the player simply ignores it when it occurs outside of a BD format. IOW, copy the movie to some other format and the player ignores Cinavia.

1) It's not the original sound quality.
2) It's more time consuming.
3) Introduces potential timing/recoding/compatibility issues.
It'd be nice to see *just one* original audio track, ex-cinavia, out in the wild
Even more interesting would be a stolen copy of Cinavia's software used for applying the watermark. I'll guess that the watermark is applied to the audio in LPCM format before encoding to it's final codec. Reverse engineering the watermark would provide a path to removing it or at least disabling it. But still I think the answer is in modding the playback device.

Is this a design flaw that can be patched by the Cinavia developers?Or is it a definitive solution?Otherwise,this will be the start of a cat and mouse game,or it could even end quickly like with DvdFab.....
I'm also curious how the audio from the ripped disc will sound on a good speaker system......but if this works well,I'm definately interested !
This "accidental" workaround sounds much simpler than all the decoding/processing/re-encoding being bandied about here .
CDan mentioned that the signal is hidden in the S/N ratio. Has anyone ever heard of Dolby noise reduction? It strikes me that this accidental discovery may have surfaced as they were simply creating an audio filter aimed at shifting the S/N ratio. Pretty cool, if so. If this is the case, it may well result in an improvement of sound quality, not degradation.

Actually, I'd say making a legal backup of a legal copy is the real pain. But, I suppose making more money is more important to the movie industry (and the music industry, too) than giving their customers what they actually want.

Its still true that Mediatek based BD players will ignore Cinavia in MKV, M2TS and other media files made from BDs.
Also true that it only triggers protection after 20 min of continuous viewing. After that you can turn off the player, reboot and pick up again where you left off for another 20 min.
I can't speak to other players, but the above is probably true even for the Sony BD players with Mediatek decoders. Whether Sony gets around to forcing Mediatek to plug those holes is another question, but the reboot trick will probably always work.

Yeah, my BD player happily plays any cinavia infested audio so I can't try the fix.
Maybe someone here has a 2012 blu-ray player, I think it needs to be made after February.
For that matter, I can play BD files through my inboard TV media player and it doesn't care either.

It appears to write a PCM header to a DTS audio track ....
Of course, a DTS encoded track looks nothing like a stereo PCM track ... so the PS3 bitstreams it to the receiver .. which begins parsing the file, recognises it as a DTS surround bitstream, and outputs it correctly.
Seems logical that it won't work if, you don't have a dedicated DTS receiver.
Also seems logical that at some point, sony will catch-on, and kill this.
Also seems logical that eventually all surround receivers will have Cinavia implemented into them.
That's true, this solution will only work if you have DTS reveiver. However, this is the only true solution to Cinavia at the moment. Any solution that is posted on here, there is a risk of Sony implementing a fix for, but at the moment, there is nothing implemented by Sony, so that is a valid solution.
I have a Samsung BD player and this workaround works for me...
If you put ANY Blu-Ray disc in the player, let it start up, then stop it, you can stream any copied BD movie without Cinavia protection interfering with the audio playback.
I heard of this workaround for the PS3, and it's worked for 3 movies so far.
Not a permanent solution, but it does get around the issue.

It seems they've prepared the software for the Cinavia module but it's not ready yet and there's still not even a rough indication as to when that's likely to be or any detail on their progress.
Kind of strange really given they were so specific about the original release date.

It's likely that downgrading the players can only be achieved by flashing the firmware though, as they deliberately try to make this impossible for end users.
Wombler
Non-reversible firmware is pretty common. My HDHomeRun tuner has no rollback firmware. It's required to keep CableCard certification. Wouldn't surprise me if that's also an AACS requirement.
No need to down grade the Sony X80 players. these were made in 2011 and early 2012. As long as no one has upgrade the firmware they will be good. I have the last good firmware saved for these players.

maybe someone cud take the audio from a movie, make a mess of it randomly and see if when u put it back together maybe cinivia gets fubar'd along the way. something that is not expected to be done to audio is often reversible thru an opposite audio effect, so two common effects may very well remove cinivia.
so i'm willing to try it somebody give me a file that u know for sure has cinivia, and i'll see wat i can do. i never fail when it comes to stuff like this. somebody check around and send me something cinivia protected.
btw , i use xbox 360, cuz ps3 is pathetic...and of course xbox user have never had cinivia problems...
but all the same, i want to be the guy that destroys cinivia as this is an abomination that must be killed before it multiplies.

Good luck to you chaotyk. This cinivia thing is such a pain. Although my kids find it humorous that if you change the year in the date, it starts working again (only for about 20 min and then you have to do it again). Anyone know why that even works? I'm technologically impaired =P
no clue as to why the year change works, but i've have had an interesting journey so far in my cinavia endeavor. so far i learned that it is hard to rip the audio from the video without some kind of loss of quality, then i learned that my good old vlc player had the solution to that. then i found that audacity wudn't open the resulting file so i had to make it into a mp4 audio file, so the file is still super high quality, then i found the little secret messages that cinavia is hiding in the audio. using audacity i found that cinavia embeds three signals, one at 15khz range, one at 20khz range, and finally one at 22khz range, these three signals pulse in and out, each using a different pattern that makes no sense, but when u combine them the pattern is actually pretty awesome, for two reasons, one it's backwards, two when turned around and played tells watever is playing it to stop in very straight forward terms..."!! :.Cinavia:.Stop Drive Rotation:.Disrupt Playback:.Display Error Message #2:. !!" the Bluray Disc player then Does As it's told, and stops and displays preloaded Error Message #2. it works on the bluray player as if u had hit a button on the remote control. so wat i did was used my own plugs in audacity to create a flanger at 15,20,and 22khz. this cause it to read as a normal part of the movie. i then saved it the file, and put it back together using vlc. and then the resulting file was Ted.avi with the new audio sync'd and a file size about 1.32gb, i the wrote it to minidvd-r, dropped it in my friends Ps3 and watched in awe as the movie played from start to finish, sounded completely normal and never got an error message. well as u can imagine i celebrated, then used his bluray player next, with slightly different results, the movie ted start with the usual universal studios logo, then pauses, the screen turns green, pixelates goes back to normal then to my amazement resumed play seemlessly as if i had imagine it, and continued all the way thru the movie no problems, then right before the end credits finished well after it had showed the names of cast and crew, it did the same thing. i believe there may be little header marks on the beginning and end of the file's video as well, but luckly without the audio triggers they become useless. so to wrap up this little experiment....F$%* Y&* !! Cinavia..I Win !! but, only for the movie ted , i still needs to try this on a couple other cinavia protected files just to be sure.. oh and Btw, i found out that i can physically hear the 15khz pattern and the 20khz, but no matter how loud i played it i cudn't hear the 22khz pattern, dunno why but watever, thot i wud mention it.

This does explain some reports of success by converting the audio sampling frequency to 32kHz, as it would kill the 20kHz and 22kHz pulses. The 15kHz pulse would probably be cut off or at least be attenuated due to the low pass filter usually applied when down-converting the sampling rate, which is done to prevent sound artefacts near the upper frequency cut off of the lower sample rate.
It's quite likely that cinema films use much lower frequency pulses, possibly even at the low end, e.g. 50Hz that would unlikely be heard during other audio and if heard, we would just ignore as just being a power hum or resonance.

Unfortunately it's not that simple as Cinavia is an "analog" watermark, so you can't search for a set hex string. If this claim is true, the software would still need to read the audio files at 1x (just like players do) in order to detect and remove the mark. We know that if you play the audio faster then 1x (say 3 or 4x) Cinivaia won't be detected by the player, so it is safe to assume the software will have to work the same way

You might as well claim that MP3's need to be converted at 1x also.
A fourier analysis of any digital audio bitstream will show the present signal frequencies, whether the CPU processes it in realtime or 1000x realtime.
If you know what you are looking for, you can remove it.
The problem is:
1) Fourier analysis takes up lots of CPU time, hence difficulty getting enough CPU time to find the cinavia signal.
2) Only Cinavia engineers *actually* know what they are looking for.
3) It's not a simple inaudible frequency injection into the original signal, it's more complex.
What is a surprise to me is hackers or those who write a lot of our freeware/ open source program haven't taken a bigger interest in
beating this cp.
In the past, many take to the challenge simply because it is a challenge....
Yet the short answer to that is most bypass it by playing video from hard drives or use older model bd players.
