Cinavia question about full ISO's

post #1 of 6
Thread Starter 
I don't understand how Cinavia can protect lossless, complete-disc ISO's? Since Cinavia is embedded in the audio track, if one makes a complete disc backup including previews, etc, won't a protected player like TMT5 see the trusted key and allow playback?

If a retail Blu-Ray disc plays and we make an exact copy of it, why won't the copy play as well?

Thanks in advance.

It is AACS which prevents you from doing that: http://en.wikipedia.org/wiki/Advanced_Access_Content_System

A licensed player will see that you have no Volume ID in your copy (it is in a place on the disc that standard hardware cannot access) and will not play it.

An unlicensed player has techniques to get around that but they are legal violations.

An old or unlicensed player will also ignore Cinavia. In that usage Cinavia doesn't need to be cracked, just ignored. The A/V is not cryptographically scrambled.

I googled TMT5: discussion indicates current versions do not respect Cinavia but future versions will.

If TMT5 is a licensed player then I am surprised it plays you backups, apart from some sort of studio-managed scheme.

The best thing to do is to retain and use only non cinavia infected equipment and players.
Refuse to purchase a standalone player licensed after Feb. 2012. Refuse to install a firmware update that infects your player with cinavia.
Refuse to purchase a software player that is cinavia infected. Refuse to apply an update that infects your player with cinavia.
Refuse to purchase blu-ray titles infected with cinavia unless it is a title you absolutely must have - make all those blind buys "blind rentals".
Teach Sony that whatever money they are giving to Verance is money wasted as it is costing them more than it is generating in sales.

The effect will probably be minimal at best, but you should vote with your wallet. I don't think the dvd/blu ray rip crowd is large (or vocal) enough to make a difference to the studios in this regard. My guess, is that they'll probably add cinavia to more, if not all of their titles, especially Sony.

The major point here is to teach Sony that whatever money they are sending to verance for corrupting the lossless audio tracks on blu-ray releases is money wasted because their overall sales figures will not increase as a result. Unless sales increase significantly as a result of paying to release blu-rays with cinavia corrupted audio tracks, there is no point to verance or cinavia.

I found that I don't really watch films repeatedly enough to rip large libraries to a NAS or computer. I would really prefer to organize a library of movie trailers or previews with simple cover art to refer to when I or guests want to watch or rewatch a movie. Many times, watching a trailer of a film will put me in the mood to rewatch again and reminds me why I purchased the film in the first place.
