MakeMKV doesn't change the audio, unless you've asked it to convert it to a different codec. Are you using the standard profile (default), or something different when ripping? Unfortunately, if the source has clipping, the options to fix it are not so great. You can extract the audio track and pad i...

Some AACS versions have new key revocation tables in them. If a drive loads one of them (even if you don't play it), the key revocation table in the drive is updated, and the revoked key (in this case, MakeMKV's) becomes invalid for accessing any BD content, including UHD. LibreDrive tells compatibl...

Again, not knowing HOW the ISO was made, I can't give you advice on how to use it. The acronym "ISO" usually means "ready to write to a disk", or "a copy of what you would write to a disk". It says nothing about the CONTENT. I can give you an ISO for a DVD that you won't be able to play in your DVD ...

But what did the ripping? Since MakeMKV does not create ISO files, it wasn't MakeMKV. You cannot make a valid ISO file without tools that know how to deal with the access restrictions built in to Bluray drives. The ISO files that result from that have different characteristics; they're rarely 1:1 co...

We need some help to help you... Did you recently try playing or ripping a BD with a version of AACS newer than v70? In your MakeMKV data directory, are there any files that start with MKB_v or MKB2_v and a number larger than 70? Version 71 of AACS has been reported "in the wild", and some drives ar...

The pitfall to selecting "best" is that, for many movies, the movie audio is either Mono or Stereo, and the commentary audio is in 5.1 surround sound, for some reason.

Not really. And, even if there were, it doesn't guarantee accuracy. The way the "signature" that such databases rely on is created would have to be decided between all parties, and someone still has to do the manual process for each variant.

The fastest way to get a response on AACS and keys is to email the files to svq@makemkv.com for Mike to examine. Posting them to the forum doesn't flag them for Mike.

It depends on what created the ISO, whether or not it decrypted the data as it did so, and, if not, whether it preserved the information needed by MakeMKV to generate a decryption key for it.

Quoting the program's author in https://www.makemkv.com/forum/viewtopic.php?style=11&f=1&t=17848#p65567 You can always download SDF.bin manually from https://www.makemkv.com/svq/sdf.bin and put it into MakeMKV data directory. On next launch MakeMKV will consume the file and shut up. I've checked and...

If MakeMKV is actually crashing, there should be an event in the Windows logs that would give more information. What does it say?

It's entirely up to the author, and hopefully he'll see your message. However, I'd suggest sending an email to support@makemkv.com if you want to find out sooner.

There is already someone offering a flatpak build, independent of Mike.

Swirls put me in the mind of "rental disk, refinished to remove scratches". Used to see that a lot with Netflix rentals. Even had some disks I returned as unplayable come right back to me after polishing (they had other identifying marks that were unique).

That's the behavior of a drive trying REALLY HARD to read a marginal section of the disk.

In your MakeMKV data directory, you should have a file with a name that starts with MKB2 for this disk; have you sent that to svq@makemkv.com for analysis yet? The name of the file should have appeared in your Info window and (if debug is turned on) your log, and it will include the AACS version tha...
