I backed up a Bluray which had a BDMV size of 23.12GB. The Decrypted backup BDMV size is only 5.94GB!
How is this possible? This wasn't an encode... I used the Backup option and selected Decrypt.
Backed up BD is SMALLER than the original?

No real way to tell without the name of the disk. It is entirely possible to put "23GB" of files on a smaller disk, if you have a lot of redundancy of names.

I don't happen to have that disc, so I can't check mine.
I'm not sure I exactly understand your scenario. You made both an encrypted and a decrypted backup of the same disc and got significantly different sized output?

I inserted the disc. Chose the Backup option. Clicked "Decrypt" and let it go.
Why wouldn't the output be exactly the same as the disc itself? What is getting compressed? I thought a backup would be the exact same file size as the disc?

And the ripping process finished without any error? (Silly question I know...)

Re: Backed up BD is SMALLER than the original?
since i have a similar question (though i'm on Windows, not Mac) i'll ask here instead of opening a new thread
i backed up Ice Age 3 3D.
File size of the backup is apprx. 38 GB.
The STREAM folder shows apprx. 35 GB
On the other hand Windows Explorer shows the disc size as 46 GB and the STREAM folder on the disc shows 70 GB.
Can someone explain why?
PS and FYI: minimum title length is set to 0
