I was able to get this ripped. I was experiencing the same issue where it stopped (for me) ad 581MB ripped for the main title on the UHD disc.

Has anybody else been able to rip this? I get a bunch of AV sync issues and it just gets stuck at Output Size: 536.0 M. I've let it run for over an hour each time and it doesn't go anywhere. Never seen this happen before.
