Redfox (AnyDVD et all) appears to be gone

Thus far I believe it has never failed to identify a broken rip. Nevertheless, it is great to have available another easily accessible tool like Xreveal's Content Hash Verifier to do verification of encrypted units on Blu-rays, despite neither one being open source.

I usually use mode 2 "advanced test" or mode 6/7 "dump and test" of BTAD. I don't know if that does the same thing as the Xreveal utility but I know it's still early days for the latter and there may still be some bugs in there. So I very much support the work to build another tool with the potential to open source it later. Maybe one of you can reach out to @nalor for input since they seem to be quite familiar with these algorithms.

BlurayTestAndDecrypt works differently. I think it checks if the Sync Bytes of the Transport Stream Header are correctly set (every 192th byte). It doesn't validates the files against the Hashtable. I don't think it can reliably detect bit flips, because how AES-CBC decryption works. A changed Bit only changes a maximum of 32 Bytes in the decryption result. (16 Byte decryption, 16 Byte Xor) But it should detect sector errors, if the complete sector contains garbage. And I think this is the most common error.

I'm very much looking forward to reading your source code once it's finished!

Yeah, took me way to long. I shouldn't look at hexdumps with a bottle of beer. It only took so long because I always overlooked adding 4 Bytes from the beginning when calculating the crc.

It's always these little things / oversights that take ages to puzzle out ...

But if it makes you feel better: I probably wouldn't have figured out that CRC thing at all (or at least not that fast) even though I never drink at all.

But I started thinking and maybe I'll add the hashtable validation in addition (wasn't aware of this hashtable until the discussion here started )

That would be cool!


I'll need a bit more time to release my implementation. It's only a side project for fun and I have a few other more important tasks currently.

Hi.

Anyone know if Xreveal will also remove region lock on UHD discs?

AnyDVD didn't do that per default, but had a regkey that needed to be set for it to do it.

Yes, I know that UHD discs are not supposed to have region lock. But never the less there are quite a few discs in the wild, where studios by mistake, or for whatever reason, have made UHD discs with region lock.

Thanks in advance

This was added in version 2.6.8: https://www.xreveal.com/news?id=81

Jeez, where has all the discussion gone in this thread?

Same with me when I'm doing a programming project.
Do take your time, real life always comes first!

Nothing more to this story. They're gone. And unlike all the stupid predictions they didn't come back under a new name and charge everyone more. They're gone.

for me on the DVD and BLURAY issue the only that can replace anydvd is dvdfab Passkey and for 4k disk makemkv is the king.

Now since what happened to AnyDVD, I imagine that they should sell the code to someone like DVDFab, MakeMKV, XReveal, or if no one wants it, why not release the source code for someone to continue with? Since it's been in development for many years. I think it's a shame, something that took so many years to disappear like this.

xreveal doesn't work ?

My opinion is that XReveal is not yet up to the level of AnyDVD and DVDFab, in terms of removing protections, it is good and could actually be a replacement in the future and I hope so, of course everyone needs to help by sending logs, AnyDVD and DVDFab have been around for several years, but that is just my opinion, by the way I am a paid user, AnyDVD, MakeMKV and now DVDFab, and I will definitely support XReveal.

So, I was using AnyDVD HD to process blu-rays and ran across the error that it could not check it's online database. This is the first time I've hit a BD that it could not decrypt since Redfox ended. I've downloaded the Anydvd database from 2020 and also the most recent keydb.cfg, but have had no luck.

What worries me is a dialogue box that says "You need to restart in order to finish setting up':F Pioneer [Friendly drive]'". I want to make sure my system is not trying to sneak in a firmware update that would brick the Pioneer drive for backing up my UHD blu-rays. Once beyond this I will look into XReveal to go along with my MakeMKV license. Just hoping drive is ok and not about to be overwritten.

The problem is that redfox seems dead and in a future more or less near, it's possible that anydvd won't works anymore.

It will stay xreveal or dvdfab.

For brand new Blueray disks redfox used their own online key database ODB. Only UHD disks used the keydb.cfg file. You may have been lucky and the bluray disks you ripped before today were stored in anydvd

xreveal has been working well for me so far. I try to avoid dvdfab because it seems way too expensive to me and their multiple different versions seem too confusing. I did use passkey the last time anydvd was taken down. passkey at that time couldn't decrypt some of my disks and I was happy when redfox came online again

Is there a way to use a local key database with AnyDVD HD?

[billqs]

I downloaded xreveal and it removed AACS but not screen pass protection. This led Handbrake to see 310 playlists all with the running time of the movie. I retried it with Ripbot 264 and it apparently recognized the correct playlist and I was able to rip it to save. This is odd as all this effort was made for a BD of a movie from the 1940s that airs all the time. I will have to test what came out of Ripbot to see if it is correct.

IIRC, AnyDVD will use the keydb file for UHDs but not BDs.

[SamuriHL]

Correct. This is why I've said repeatedly that AnyDVD has a shelf life. It'll work for UHD as long as you have an updated KeyDB.cfg but it will not do anything for you with new BD's. it MAY continue to work while the current MKB isn't changed but it may not.

Like all of you, I'm a Redfox orphan. Namely, I've been using AnyDVD(HD) for over a decade, purchased two lifetime licenses, etc... I used to rip the occasional video Blu-ray but, most of all, to rip the hi-res/surround audio from Blu-ray discs, both audio and video.
I keep reading here and there suggestions of DVDFab Passkey as a valid replacement and I beg to differ. Here's my experience with those guys.

Without first testing the software (I'll admit that was very stupid of me, but I never had a single issue with AnyDVD so that probably made me careless), in the aftermath of Redfox's disappearance I purchased a DVDFab Passkey lifetime license. Well, the very first Blu-ray I tested it with (SDE's Wham! 'Make it big'), it wouldn't load. Reading error.

I contacted their customer 'service', who gave me the usual series of questions/tests that never solve a thing. Then they asked me to send me a series of files from the disc. And the waiting started.
Meanwhile, I could see that MakeMKV (for which I purchased a license a lifetime ago) could load that very same disc without any issue whatsoever.
Later on, I decided to buy the Xreveal Pro license. Surprise! Xreveal could also read that Wham! disc.

So I got in touch with DVDFab customer 'service' again, informed them about my findings, and, with the occasion, I also told them that Passkey could not read two more recently released blu-ray discs that I had meanwhile purchased: Fish 'Vigil in a wilderness of mirrors' and 'Internal exile'. But, guess what?, Xreveal and MakeMKV could read those too. No issue. Again. So I send them the files from those two discs too.

Time has passed (I'm talking months); Passkey has had several new releases but those three discs remain unreadable by that junk software. And hear this: when I tried to ask DVDFab for an update on my ticket I found out that... I could not! Somehow they had blocked the 'reply' feature within my still pending ticket. I made sure of that since I tried with other PCs / browsers. Now, that was a stroke of genius. I was officially baffled.
What I did was to open a new ticket (I know, why bother?) to inform them (like they wouldn't know) that those three Blu-ray discs still wouldn't load, and that I had realized they had blocked me from replying.

Bottom line: as long as there's an alternative, I would not consider DVDFab software as a Redfox replacement. It's junk. It may work, but then again it may not. Be advised.

it seems that start from 2.6.x, xreveal will not support aacs-auth on free version.
PS: I tried new version, and it asked for online decryption while I can use VLC with the same keydb.cfg to play the disc, so I rolled back to old version

I've already puchased makemkv, so I think I will stick with 2.6.0 in case of blu-rays containing BD with MGVC.
