    I thought that was the point of AACS. They could patch any compromise that came up and there wasn't one 'master key' that could open them all and was irrevokable.


    EDIT
    Any system that has a single irrevokable key is destined to fail at some point.

    The details are secret and finding anything about this on the net is difficult because it gets removed.
    Loads of people spout off opinions when they may not understand it themselves.

    It wouldn't suprise me if the BD camp leaked the AACS codes in order to scare the HD-DVD studio's. Can you imagine the ramifications if there's no protection for HD-DVD titles? Fox was wise to push for BD+ it could in the long term save the BD format.

    Out of interest, has there been any HD-DVD titles ripped to the internet so far?

    Yes, a few HD-DVD are about. 7 when I just counted.

    The key was leaked by AACS themselves, apparently.

    Why would Blu-ray leak their own key and why would Blu-ray 'people' have access to the HD-DVD key?

    Edit: I suppose if they think BD is unbreakable. Hmm, **** poor strategy if they give up a half their security to win a war they have already won.

    The story, and the link to the principal site they are talking about is on BBC news. Currently, AACS is ALL BD have, so I find the likelihood of them being the leak very small. Even though I don't think they think the war is over, they are digging in for the long haul. BD+ on it's own may not be enough anyway, no doubt there'll be a horde of hackers onto that. Nothing is uncrackable these days, the hackers could just link in to the folding programme, and get the PS3 network to do the slogging for them, LOL! Seriously now, copy protection is history. People are not doing it for profit, but just because they can. And just like the infinite number of monkeys and the script for Hamlet, enough people trying and it will be broken.

    There are loads of hd-dvds and blu-ray discs on the internet.

    Some have been downsampled to .wmv files or .ts files.

    Yep, plenty of both knocking about... which does make a mockery of all this :D

    But I agree with MAW it's more about beating 'the system' than profit.

    I'm also aware of a number of HD titles of both flavours doing the rounds. No personal experience, my PC is not connected to my AV system, I have enough of PCs at work thank you, but the file sizes look right for undoctored HD movies. So the hack must actually work.

    But there were a number of HD DVD and BR rips already posted coming out of Muslix84 efforts a few months back. Do we know the new key release is currently having a similar effect?

    Why on earth would AACS leak a key? This seems completely inane to me!

    I'd like to read some more about the BD-J protection and how it compares to the current AACS standars on HD-DVD and BluRay.

    The Studio's must be having kittens.

    I've had HDTV rips before but how can you tell these HD rips are specifically from HD-DVD and BD?

    Lets put it this way they are identical in everyway to the disc's i have bought ,the full rips contain all the ads and full audio either pcm ,or truehd ,depending on which fromat,powerdvd info file tells you the bitrate and audio of the movie playing.

    Also the size is a bit of a giveaway tbh.

    If AACS were to become useless and BD added other protection measures, which format would consumers prefer to go with; HD-DVD or Blu-Ray?

    Because the entire content of the discs have been rippped and posted around the net. Fireup PowerDVD and use the play from hard drive feature and you wouldn't be able to tell it wasn't an actual disc playing.

    Even with the downconverts it's pretty easy to tell since the quality is still HD (720p). Plus any equivalent broadcast verison will generally be of lower quality and have artifacting present.

    Personally I buy movies I like and always discard a tv version once a Blu-Ray or HD-DVD verison becomes available.

    So you're saying the titles are available as 720p, not 1080p? 1080p would be so large as to be impractical -- 720p is probably MUCH more attractive for downloading. Of coarse, the quality of the encode may not be the same. Still, it would be free, and I guess that's the point.

    Consumers will vote HD-DVD. They don't give a damn. The studios, that's another matter. Just how big a problem is piracy to them? We all know the rips are out there, but the majority here would appear not to download. It's just so much easier to buy the disc, then it's yours. They're not that expensive.

    Agreed, and as the price drops, that will make purchase even more attractive. VERY few will be interested in downloading 10GB+ movie files.

    That's the other angle though isn't it. If the AACS key was released purposefully then it may have been to move the studio's away from the then insecure HD-DVD to the potentially secure Blu-Ray.

    The 'extra' BD+ security (if it is that) is TOTALLY dependent on AACS.

    Are you saying that if AACS is compromised then BD+ is also compromised at the same time? :suicide:

    Surely this is old news anyway which goes back to last December when this fella 'muslix64' managed to find a way around the AACS on HD DVD shortly followed by Blu-ray, so please, no conspiracy theories :boring:

    I should think most people who are ripping HD discs now are using Slysoft's anyDVD HD which is such a simple tool to use. As has been mentioned before the size of these rips can be huge for downloading and the price of recordable BD media is probably more expensive at this point in time than buying the original disc.

    IMO the appeal of ripping will be for playback from HDD, at this point in time only the complete disc can be ripped and the storage size needed is prohibitive. I have 1 HD DVD and 4 Blu-ray discs ripped which takes a total of 157GB :eek:, once we see rippers where you can just choose what content you rip the appeal will be greater.

    Anyway, a few choice quotes from Slysoft team members on their FORUM

    It seems these guys are very confident.

    Just picked up this link which I think gives a more complete picture of the situation:

    http://www.dailytech.com/AACS+Key+Censorship+Leads+to+First+Internet+Riot/article7129.htm

    Seems there is no new key release and there is no AACS key leak -- that was all misunderstanding/missinterpretation. The fuss is purely about the AACS trying to shut down the publicizing of keys on the internet.

    The OP's link really had me wondering for a while there.

    In spite of the spirit of the link, it appears that Peter's thread is correctly titled, and it also looks like he could have put BD+ in the title too. Though clearly, as it's yet to be made to work in the 1st place, only time will tell.

    The question might not be about what choice the consumers would go for, its what the movie studios would go for. They all want control on their products, and whats more secure.. AACS and its potentially easily ripp-able (is there such a word?) content or BD-J?


    Nic, I'd like to hear more information about BD-J and its reliance on AACS if you have any links. Cheers. :)
