AACS did actually work pretty effectively. Keys were discovered and then revoked. You could play old disks but not new ones.

Similarly afaict there are some sketchy closed source programs to remove cinavia,but given we are a decade in, and there is no open source implementation/public description, i would say it lasted better than i would expect.

Definitely not a total success for DRM, but better than many people predicted.

Well... no. Right now there are multiple software packages available from questionable sources that break AACS offline on-demand no problem. So... yeah.

As for Cinavia, if you shift the pitch of the music, you can cause the player to stop recognizing the track. Or, as some people have experimented with, you can compare the audio to a version of the film from alternative sources (i.e. streaming) to detect and patch over potential watermark signals. Or, well, burn a streaming rip to the disc instead of the disc encode.

Including disks with the latest MKB?

Sure, but that distorts sound, which people dont like.

Like its definitely not totally blocking piracy by any means, but its certainly not totally defeated the way DVDs DRM was. Its still present enough to be a little annoying, which is much better than early predictions thought would happen.

AFAIK, it appears so. Also AACS LA appears to have given up and stayed on v68 for a few years now. Maybe there is a new one at last... maybe. AACS 2.0 it sounds like started from v72 and counting up.

> Sure, but that distorts sound, which people dont like.

True... but if I just burn a stream rip instead to the disc, problem solved. Plus most discs do not have Cinavia.

From what I can gather... you can just download MakeMKV and rip Blu-rays on any PC Blu-ray drive, no problem, no internet connection required, latest MKB, BD+ completely defeated. It's only annoying if you are trying to actually copy the disc.
