Re: Thank you.,,,doom9 site and forum are for much more than just cracking drm most video/audio/player developers post and collaborate there they also have excellent video codecs comparison tests, ie is xvid better than divx better than x.246 | |

I Know what you mean. I use DVD Shrink to copy all of my favorite Miss Marple DVDs that I check out from the library. Although BBC does encrypt the DVD they produce I use DVD shrink to shrink 8.5 GB to 4.7 GB. | |

Wow, I didn't realize it had such a glaring weaknessWhat's the purpose of a "processing key"? Why introduce a weakness like that into their protocol? | |

Re: Wow, I didn't realize it had such a glaring weaknessThe processing key is the Bob of the Alice and Bob crypto schema. In order to encrypt a disc, you need two things, a public key (alice) and a private key (alice). For Bob to decrypt something from alice, he needs to know Alice's public key (i.e. the HD-DVD). That's what the studios are looking to 'blacklist', so if a player is compromised, they could make the new dvd's NOT work with that player. Thus, every HD-DVD and Blu-Ray contains a section of 'disabled' players (public keys).
If what he said is correct, he's found alice's PRIVATE key. With that key, you don't need to care about the public key. EVERY DVD uses the private key, so you can decrypt everything. | |

I don't claim to be a crytologist, but I think I'm missing something from your explanation. In asymmetrical encryption, there are two keps. Private and public. Something is encrypted with one, and then decrypted with the other. The key that did the original encryption can't also be used to decrypt the cyphertext. | |

I can't remember the source of the information (Ed Felton maybe, at Freedom to Tinker?), but if you read the history of these DRM methods, it appears that some decisions have been made based on things such as how many circuit cards would be needed to implement the DRM - the circuitry for really robust DRM would take 2 ckt boards, but this would add cost and the decision was made to go with a one ckt board, less robust "protection" to keep costs down. I'm not saying that's why this weakness occurred, just that these DRM schemes are so easily compromisable sometimes because of decisions like these. | |

Ever seen a downloadable movie before it was ever released in theatres???? Well, DRM is just one aspect. The problem also resides with industry insiders. A combination of DVD screeners and DVD masters end-up on the net....
The solution is not DRM. Just like for music, DRM hinders and limits the honest users and not the crooks. If the price is right, people will stop bothering with pirated copies... If you ask me, it's a shame to pay 25$ for movies like "click". | |

Re: ...Single layer BDs are 25GB, Dual layer BDs are 50GB.
Crank is 49,898,065,940 bytes. Pearl Harbor is 47,568,993,406 bytes
Close enough to 50GB. BIG ass file sizes
Stripped down to JUST the movies themselves you are looking at 21-29 GB average. Playback can reach 40mbps+
*FOR ME* file sizes, at my current internet speed, dictates that sharing isn't going to happen. | |

I Don't understand encryptionI have no idea how it works, zero. However I've seen crackers go in a defeat encryption on DVDs, HD DVDs, Blue-Ray, WiFi, etc. It seems to me encryption is pointless and if anyone wanted to access your info, be it the FBI,NSA,China, or a private person they can. SSL, TrueCrypt, etc are all crackable.
Someone help me out here, I'm not being sarcastic when I say I don't know. What's the difference between breaking the encryption on a DVD vs breaking the encryption used on packets via SSL or even an encrypted drive using TrueCrypt. | |

You are missing the pointI don't think the point of DRM and encryption is to keep out the hacker or even well educated computer person. The idea is to keep 95% of the public from duplicating and sharing the files. There is no need for a bulletproof prison, just a hurdle big enough to keep the casual user at bay. | |

Compressionis it true that the 25gb rips ive been seeing on usenet and BT are already in a compressed form??? What I mean is DVD's for example are shrinked from 4.36gb to very good looking 700mb xvid rips imo...the hd rips we see...are they already compressed or would that defeat the whole purpose??? just curious as i am new to this HD thing...i still plan on rockin xvids for a long time | |

Just give up.You're making a fool out of yourselves, and just alienating potential customers who are sick and tired of all these stupid limitations.
Ideally, they'd like HD-DVD and bluray to be a standard. If I can't make a lower quality copy of a few episodes of a tv show I watch for my PMP, that's it - the format is useless. If I can't use it the same was I can use DVDs, then I don't care about the quality, it's useless for me.
Thank usenet. Thank the people who, during this silly ordeal that will continue on and on, will continue to ensure it's possible HD content be playable on as many devices as possible, with the least limitations. Thank people who for no money are working to get you content better than what people who're being paid for get.
The protection doesn't work. It's a bottomless pit of money for whoever is shelling out the money to develop these ass-backwards protection schemes. | |

Cost vs piracyThere is some pretty good discussion of piracy issues and encryption in this thread. I've enjoyed reading them. I think one thing that many people don't take into consideration is that if the cost of music CD or DVD movie is reasonable then the majority of people will not be motivated to make or obtain an illegal copy. This definitely holds true for me. I'd much rather buy a legal CD at a good price than spend the time it takes to locate the music and burn it to CD, then make & print a cover. As far as today's music goes there is so little out there that I would even want to buy, especially at the prices they want. If record labels and Hollywood want to reduce piracy, they should reduce prices. I'd bet they would be pleasantly surprised at the increase in sales and profits! | |
