Looks the same, thank you.

Disk wouldn't rip. Sent in a dump file.

TL;DR - I got Aliens to work after replacement disc

Bought Aliens 4K UHD from Amazon

First disc didn't rip, got errors. Tried multiple times and even copied the disc to hdd first. No luck.

Replacement disc worked, first time.

SUMMARY: The first disc I ordered from Amazon errored out. The second disc ripped fine. Bought the 4K UHD Disc from Amazon. I tried the first disc 4 times and it always gave read errors. I even tried copying the entire disc locally first, which was successful but also gave errors about hashes not ma...

I ripped both 0062.mpls and 0063.mpls and couldn't tell the difference.

I watched 0062.mpls all the way through and it looked correct.

I'm just going with that one for now.

Looks like 0064.mpls doesn't have as many language or subtitle tracks as 62 and 63, so we can ignore 64.

0062.mpls and 0063.mpls both have the same number of chapters. I ripped both and confirmed all the chapters match visually.

I haven't done a more in-depth analysis yet.

Thank you.

Apologies in advance if this is the wrong forum. THE PROBLEM: The 4K Blu-ray of Ghost in the Shell has the wrong song during the credits. THE SOLUTION: You can copy the correct audio track from the 2K Blu-ray MKV over to the 4K Blu-ray MKV. (Takes about 20 minutes.) I'm posting this fix in the hopes...

I get this debug code when trying to rip a second 4K bluray. First bluray rips fine, but I don't think it's a disc issue because rebooting fixes the issue, allowing me to rip the disc. Attempting a second disc causes problem to return. The workaround is to reboot after each disc. DEBUG: Code 3221225...

Amazon (US) release now works fine. Thank you!!!

I also had a failed decrypt and submitted my dump file.

EDIT: (US Amazon release)
