Automatic Blu-ray Backup?

[geuisteses]

Please, excuse the non-knowingness of my question(s). Spent the last couple hours reading through various faqs and such to get myself caught up on backing up blu-ray and DVDs.

I have an end-goal to build a system that will automatically backup our DVD and Blu-ray disks. I want to be able to drop a DVD or Blu-ray disc into the machine, where it will be automatically ripped, transcoded, and stored.

I am pretty confident I can do this with DVD with little to no problem, but the Blu-ray part has me concerned. I know that newer disks frequently have new keys.

Is my end-goal for auto Blu-ray backup dead in the water? Or, is it possible to string together the right programs to get it done with just the occasional tweak to add new keys as needed?

I'm not asking for someone to figure this out for me. The fun is in the doing. But I would really appreciate some feedback about whether its possible or not, and some tips about software to start with.

Much appreciated.

Because of the untold future of BD/+ and HD-DVD I would say that what you are implying is rather hard to get hold of...:confused:

The problem is Sony is hell bent on content control (ie MKB4 and BD+) that every time someone finds a way past there DRMd disks they blast that out of the water with software, Firmware upgrades, new keys, random generated keys ect. :rolleyes: The list goes on...

The way I see it is; If you want something like that. You will need to be a frequent visitor and contributor and maybe all together devoting time and talent you might be able to reach your goal...:)

AnyDVD HD will decrypt all BluRays, even MKB4.
So if you're running Windows, it's the easiest choice.
As long as AnyDVD is running in the background, you can use any program of your choice to do the copying (even xcopy from a batchfile) :)

Can AnyDVD HD be run in Wine on Linux, say Ubuntu? One thought I'm researching is to use the Handbrake CLI to backup regular DVDs to mp4. I might be able to do something similar for the BD discs if AnyDVD can run under Wine. If not, I'll have to figure out a similar solution in Windows.

Hey thanks for the advice guys. This should be fun/frustrating to figure out!

Not that I have done it. If you already have a Windows system - a vmware player might do a better job. Just install AnyDVD and 'convert' it and then play it using vmplayer - both VMWare tools are free.

My work computer as a vm runs better on my minimac than on itself as a real machine!


edit: Actually it might go better the other way around. Run windows + anydvd and 'mount' it with a Ubuntu vmplayer appliance.

All bluray, except ALL BD+ Bluray discs, EPIC FAIL!

You can rip BD+ titles to disc and play them from there with earlier PowerDVD versions like 3104 and a few versions above that. EPIC is such a big word :cool:
You can't process those rips though, like transcode or play with an arbitrary player yet, that's correct.

But I have most of the BD+ code done, should take no more than a few weeks, I guess... (the details and lack of documentation are a pain ;) )

Nobody else has found keys to decrypt the MKBv4 discs. EPIC fail to all the others.lol

Thanx peer. Hope you can finaly reverse engineer the BD+ code.

Peer van Heuen for president! :D

How is it that it takes the movie studios years to develop this encryption standard and slysoft just come along and break it so quickly? Whats your secret to success?

[oddball]

Because big business hires muppets :)

Amen to that. I cant wait for full BD+ support.

10 years?!? Does this guy live on earth?

You guys rock! Thanks for helping Sony and company out.
Cracking bd+ will likely increase blu-ray drive and disc sales...

Oh the irony:

DRM was the main reason Blu-ray won the war (it won over the studios)...

Yet it is the main technology that failed to deliver what it claimed LOL!

[Adub]

Amen.
Now, we just have to wait for it to be proven that BD+ is broken. And we still are having trouble with MKB4.

[phigment]

Just a thought I had last night.

Maybe there is something I am missing, but I don't really think BD+ can be 'broken'. Part of the idea behind BD+ is that it can modify content as part of the decode process.

Let's use a simple example.

The studio takes it's content and inverts all the bits before encoding. This would look like crap if decoded and viewed as is. So as part of the BD+ microcode it says, "after doing the bitstream decode, flip all the bits in the video stream".

Now, even if a BD+ VM was created, and we could extract the orignal bitstream from the disk, to get the content we would also have to apply that bit invert to decoded video. Thus we wouldn't be able to have a decrypted bitstream playable by another H.264 codec, such as CoreAVC. If you want that, you would need to decode, apply the transform as coded into the BD+, then re-encode.

Any thoughts?

i had a similar thought (see my other post) and as I see it, no need to re-code. The player replaces parts of the bitstream before decoding.
my concern is this - there is a piece of hardware in the player, which does a one or more functions (replace bitstream)
by command. this command can probably be derived from studying the java virtual machine, but in case there is a certain hardwired function, you can then tell that one is done, but you cannot tell what is done.
As i suggested earlier, nero 8 seems to identify 'faulty' parts of the stream and not display them. That means it can identify the parts which need to be worked on.

the worst thing would be if the bitstream looks exactly like it should look, but still makes no sense when decoding it.
an easy example would be to shuffle frames or gops by some scheme.

well i hope that people who understand better than me what is going on will find a way to solve it...
