As he said, he has no Blueray drive. If you want to send him $500 so that he can buy one, I bet he would really love that. Seriously, seeing as how you haven't done anything yourself, you have no room to criticize. |

At last I can post...
I found the keys for Swordfish and Training Day and was able to decrypt them using BackupHDDVD but when played it's just a black screen with no sound. King Kong is fine and by fine I mean a jittery mess but at least that's what everyone is getting anyways. So what's up with these 2 Warner Brothers movies. Is it cuz of the added stream for In-Movie Experience(IME)?

C = AES-128CBCD(Kt, Ce) so no talking about content key Kc. I was referring to the HDDVD AACS prerecorded spec http://www.aacsla.com/specifications...rded_0_912.pdf section 4.3.2 where the pack encryption is described. and where the content is encrypted/decrypted with a variant of the Title key. But maybe it's only HL_PCK packs that are encrypted with a Kt variant (Kc) and so if such packs are encountered, they won't be decrypted correctly by backuphddvd. |

With full respect, apologies to anyone who took that as a personal attack.
Now, doesn't anyone here have a Blu-Ray drive of any sort? Using it with the Power DVD software should allow the keys to be seen in the same way. It seems right that one should be able to back up one's Blu-Ray discs as well. Let's get a head start until someone releases a mod'ed version of "backup". |

Unfortunately I don't have any of the requisite hardware, software, or content to experiment or I'd be digging in; all I can do is watch from the sidelines and read the publicly available specs and code. |

i.e. Bytes 4-19 of the MKB (MKBROM.AACS) = Dv and [AES_128D(Km, Dv)]msb_64 == 0x0123456789ABCDEF Last edited by The_ByteMaster; 16th January 2007 at 19:50. Reason: clarification |

If that formula is correct, and my recollection of the spec is correct (I don't have it in front of me here), then it would be difficult since Km (I think) is the "media key" - which BackupHDDVD doesn't have and cannot get from what it does have (the Title Key and/or the Volume Unique key ). In fact, it's the reverse that happens in a normal player (the media key yields the Kvu and Kt).

The Volume ID and the Km (media key) are used to create the Kvu (Volume Unique key), but this step is not reversable (AESG) But if the idea is to check the correctness of the Kvu, another possibility exists using the TKF (Title Key File). The last entry of this file is the TKF MAC: This field stores the CMAC value of the data ranging from the 0th to the 2463rd byte of the Title Key File. The key for the CMAC calculation is the Volume Unique Key (Kvu). |

Thanks Muslix64. It may be that we have to wait for a stand alone BR drive that can be accessed by an operating system before that get's worked around like HD DVD now is. EDIT: If this is considered off-topic, I am sorry. I'll delete if requested. Last edited by tdent1138; 17th January 2007 at 03:43. |
