Adobe Encore -> CSS encryption

[shdwsclan]

Before we started, I get poinlessly shot down here are the faqs.

I believe that anyone who, knows how to rip dvds = more power to them, hell I've even done it. I know its a flimsy protection scheme. There are also two types of CSS, '

Your basic = I have encountered in most dvds that I backed up, and you can use the program you googled.

Your wierd = I've only encountered this when backing up my beavis and butthead dvd collection. It seems the CSS emulates a regular disk, but in fact elsewhere and in this case you need a more sophisticated piece of software.

My belief is that CSS is only there to stop the stupid newb who doesn't know what google is. Note: there are a lot of these in america, even if they have dvdrws...they dont know how to use them.
The only method they know is the Drag-and-Drop. This is where I come in, and I want to stop this.

Also, I dont believe in region coding at all and I dont support it. In the begginning DVDs were supposed to be region 0 and have all audio and subtitles available anywhere, sort of the idea universal world dvds. Dvd players were supposed to be region free, and have automatic video system conversion, but thanks to capitalisic idiocy, we have what we have.

Ok, so that I have cleared everything up and I hope that this post will be about the problem at hand and not the implications of using CSS.

I use Adobe DVD Encore, and have been getting a " sector header" error while trying to write this to dvdrw/dvdr. I am using the copy protection setting.

I know that commercial dvds are have data arranged closer to the edge of the disk. DVD-R/DVD+Rs have data slightly offset, DVDRW dont have this problem and you can play dvdrws in some older dvd players that wont play DVD-Rs.

Is it still possible to add the css feature to a burned disk.
I'm not sure if I am right, but dvds must have a subheader where this css data is written to, where home dvdrw drives just cant write this header.

Am I right,
is there no other way to encrypt VOB files

can you bypass the encore error message
can you make a consumer drive like my Pioneer A05 write the subheader, or write the CSS properly.
Can you make encore create a DVD image with css that is COMPATIBLE with "set-top" units and not PC based software player so that it can be written in a program that can force the subheader.
Can you encrypt dvd images, the pros must do this somehow, even if they move it on dlt tapes to the pressing facility....

Basically, how can i apply this CSS encryption??

No. You can't add CSS protection to a burned disk as the key portion required to decode it can only be put on a disk in the pressing process. The section of the disk you need is not available to you in the burning process.

There is another encryption option that may work, although it doesn't work on all formats of disk, and it will, like CSS, require a licensing fee be paid per disk.

The only other suggestion that has any merit that comes up during these types of discussions (amongst the usual moron type comments) is to include in your structure several hundred MB of blank video that isn't referenced within your DVD at all. Locate the physical part of the disk on which this has been burned, and scratch it so it is unreadable. This will make most attempts to copy it very painful.

I know that Encore boasts some form of protection, but frankly, I have never seen it actually protect anything. It can't be CSS because of both the physical limitation, and the fact that CSS is a per disk licensing fee that you would have to pay seperate to the cost of Encore. My sister-in-law's dancing school gets a semi-pro to video and edit their concerts. He uses Encore and his advertising blurb and DVD covers all boast of the copy protection. But you can copy the disks without using any sort of ripping software - just a simple disk copy.

Frankly, Encore seems to be full of claims that just don't have any merit.

I understand that this portion cannot be accessed by ordinary means, but I do know it can be accessed....somehow but the process is probably inconcievable complex...I dont want to do that.....

Look at DiskJuggler and the incredible job it can do with backing up DreamCast games.

Please elaborate on this "other" encryption option...

It's called CPRM and you can read about it here -> http://www.disctronics.co.uk/technology/dvdrecord/dvdrec_copyprot.htm

I don't know how widespread it is, or if there is a consumer application of it available.

[shdwsclan]

Out of curiousity, are there any commercial dvd pressing machines for sale, or is there any company that makes such dvd pressing machinery.

These machines must exist and they must be plug and play because why would Encore have such a feature if there were no application for it.

The machines can be possibly described as possibly feeding off a roll of calcadinide and pressing it on to clear disks. Its not very likely that every disk pressing company out on the internet built their own machine, especially if its iso 9002 standard.

In the mean time i will read about CPRM/CPPM. I've encountered such encryption before, I remember, if you use a static css key search, it will find an incorrect key or no key and will yield incorrect timecode, or just black video on there rip. When using dynamic css decrytion, the video is easily decrypted and there are no proplems.

There must some way of implementing CPRM/CPPM without the fees, I'll have to ask my ACM chapter about reverse-engineering css and open-sourcing encryption, but this may yield fruitless.

Not the sort of thing you find on eBay, and you still have to get CSS keys generated by the CSS consortium on a per disk/title basis, and pay on a per unit basis.

But good luck, cause if you can get something that works, the studios will beat a path to your door.

[shdwsclan]

Yeah.....and a herd of lawyers from the
css consortium
mpaa
and probably most of the world's top hardware/software manufacturers.
