It is clever, but, it does have drawbacks, too. A lot of people are complaining about having "offline HTPC's" but then, how do they get AnyDVD updates to that machine in the first place? If they're that concerned about putting the machine online to allow it to crack discs "instantly", they can always wait until AnyDVD is updated with a new key database and update the AnyDVD version "offline". So, yes, people are complaining already about this new method, however, given that it's the *ONLY* method so far, well, not too much to complain about IMO.

The "solution" is sequence keys which would (eventually) identify the compromised keys used by the oracle. As others have commented, it's likely that the keys came from a software player and they will all be changed by AACSLA on the next MKB cycle. Sequence keys may never be used. I suspect that Slysoft sees some advantage in hiding the keys they use from their competitors, and some advantage in keeping secret which software player they have compromised to reduce the incentives to harden it. |

That's not really the point. We simply found that there are several advantages to it. One is: yes, software players have put tremendous effort into hiding their keys lately. It took me a full 3 weeks to get them, after all, so my hat off Anyway - while this may encourage people to start hacking into AnyDVD (which is happening all the time anyway for cracking purposes) - AnyDVD does hide it's keys too, but not as efficient as the latest SW players do, I have to admit. So it would make me feel a little awkward to put all that work into the unwrapping and then see our friend FengTao just copy them from us (which I would do too in his place, I'm not blaming him for that at all). So instead of adding that amount of hard work to obfuscate keys as well as current SW players do, we decided to not put the keys into danger at all. Also, this method let's us be right on top of the news, whenever a new encryption comes up, which is the point that has the most sex-appeal to me myself EDIT: there are some additional advantages to the users as well, like SAK/PS3-users using 1:1 images created from their PS3 will typically not have to wait for an AnyDVD update that can crack their known disc - the online query is much more up to date.

But I see you point, and when I think about it, it would mean that AACSLA would know exactly how to unscramble the keys. =( |

It would have been nice to know what you learned about the obfuscation/hiding and how you learned it - purely as an intellectual interest - but I understand that you probably don't want to tell your competitors, those who wrote the obfuscation/hiding routines and the AACS about your techniques and failures/successes. Perhaps one day, though ... |

Well, hats off to Peer!
Now to BD+. SlySoft forum users (at least 2 of them) report successful ripping of the BD+ title. http://forum.slysoft.com/showthread.php?t=9120 SlySoft itself did not say new AnyDVD breaks BD+, they said they are working on this. But..can it be that BD+ has no clothes? Just complying with the file structure does it? Wishful thinking I guess. |

Please keep such comments regarding other members here to yourself or on your own forum. Apart from possibly being libelous (which Doom9 might also be liable for), it is clearly a breach of rule 4. We do appreciate your participation here, but please be aware of our rules. TIA. Regards

It is starting to look as if there might be a bug in a software player (as if) that is facilitating by-passing of bd+ somehow. I imagine that exploits of that are a separate matter to progress being made elsewhere. |

For those who haven't read it, it says that if you rip a BD+ title with AnyDVD and then normal file copy the missing folders, BD+ can't tell the difference from the BD and the harddrive, so it plays back the movie perfectly. Who would have thought that BD+ is independent of the AACS DRM? |

Somehow I get the feeling it's not supposed to be. Most likely it's a bug in PowerDVD that will eventually get patched. However, it's quite interesting for now, for sure. Now if I could only get my darn PS3 to play nice and allow me to image my Blu-ray discs to my external drive I'd be golden. Almost there on that one. My new HTPC components arrive sometime next week, so, I'm definitely ready.
