Copy-protected copies

[setarip_old]

One of the older, computer-savvy grandkids was visiting - and asked if he could watch ''Stranger Than Fiction" in computer room. After an hour or so, he returned to my office with a very frustrated expression on his face.

He told me that, before watching my backup copy (I never permit using my original, purchased DVDs for viewing), for "kicks and giggles" he tried to make a copy of the copy. Multiple attempts, using the programs he's familiar with (DVD Decrypter, NERO, DVD Shrink, Windows Explorer), all failed. Since, as far as he knows, backup copies are decrypted, there's typically no problem duplicating them.

What he wasn't aware of is the fact that I had used "RipIt4me" in ".ISO" mode to make a true 1:1 copy, including the "ARccOS" protection scheme,and had burned it to a DVD9.

So, if you are one who worries about unauthorized copies being made of your backup copies (containing "ARccOS" protection), this would be one method of preventing some people from doing this ;>}

He needs to get just that little more savvy, then he'll have your measure! :) Invite him to Doom9.

I'm afraid you've missed the purpose of my posting...

yes and no ;)

blu intended to say that if your grandkid would be really that 'savvy' he'd detected that your copy was/ is still protected :)

Tried to use Windows Explorer? Talk about desperation.

I think the grandkid wasn't just that savvy, you can't make a true 1:1 copy including ARccOS for two reasons:

1.) You can't burn CSS

2.) You can't burn damaged sectors

Therefor it should be no problem to make an ISO-Image which plays just fine as the first generation copy.

:rolleyes:

@KenD00Therefor it should be no problem to make an ISO-Image which plays just fine as the first generation copy.The backup copy, while not containing CSS, DOES include the "ARccOS" protection scheme. Although the bad sectors are replaced with padded sectors, the original "weird" .IFOs (Up to 99) are PERFECTLY REPLICATED.

This leads to DVD Decrypter, by itself, crashing in "ISO read mode" (as well as in "File mode" and "IFO mode").

It also leads to DVD Shrink generating a "cannot continue" error message.

Of course, both NERO and Windows Explorer reject the DVD out of hand as being copy protected.

I'd suggest to you that as far as successfully making an .ISO image of this DVD, one would have to do exactly what has to be done with the original, commercial DVD.

By all means, you should try it yourself ;>}

thanks again for your colourful explanation but I already understood you the first time... :rolleyes:

[setarip_old]

but I already understood you the first time...Thanks for clarifying! Glad to hear that ;>}

BTW - The eldest of grandson REALLY likes your avatar!

you know this is what i ment when i was asking for help, in this topic http://forum.doom9.org/showthread.php?t=127853,
thanks for this this information will do me wonders....... :)
but I dont understand this '"ARccOS" protection scheme" how do u get it or yeah.... im quite a noob at this... as you can tell. this is new for me

[setarip_old]

but I dont understand this '"ARccOS" protection scheme" how do u get itYou can't "get" the ArccOS protection scheme - it has to already exist on a commercial DVD...

[burfadel]

He just used the old DVD Decrypter which doesn't support newer protection methods. If he used DVD fab decrypter, he would have succeeded without a problem :D

I personally couldn't care less about persons making unauthorized copies of my backup copies so long as:

1) I don't know about it

..and...

2) it doesn't lead back to me

:p

I'm curious. I use Ripit but I've never used alone. Can you explain the steps you used to make a true 1 to 1 copy using Ripit alone or point me somewhere on here that does expain it. I may wish to do this too! Thanks in advance.

:pI think if you lend someone a copy, and they copy it without your permission, you're not to blame. Much like if someone were to steal your original and copy it, you can't well be blamed. Although there's probably some law that says you're responsible for protecting it and blah blah blah. >_>

The steps are in the first post in this thread. You can't do it with "Ripit" alone because it does not burn.

There's an even better way to protect your original copied DVDs. That is if you're watching them on the computer...

Go get TrueCrypt (www.truecrypt.org). Get your backup ready for burning, and make a container. Put your DVD files in there and then burn that to the DVD. What you have just done is encrypted the DVD and the only way the DVD rom can read it is if you type in the passphrase to decrypt it. Optionally if you're like me you would also create a key file that can be stored on a USB drive that needs to be present along with the passphrase in order to decrypt. Otherwise the DVD shows up as a blank DVD and cannot be read. :)

Would be kind of cool if you could somehow load truecrypt on your DVD player :).

[HyperHacker]

Well, a lot of A/V equipment these days is just a customized PC running some form of Linux. ;)

It seems a bit hypocritical, though, to go remove the copy protection and then add your own.

[blutach]

Gee, there are better ways of encrypting anyway. For private users, I particularly like Junior73Italy's ideas in his DVD Copy Protector (beta version was published a year ago). This was a forerunner of the DVDXProtect (or whatever it's called) scheme seen in Germany over the past year or so.

I like the idea of putting them a samba share with a required username and such
stuff it on an encrypted zfs or another comparable FS and bobs your uncle
