Hopefully I am using BDRB as designed; I understand it processes UHD 4k files. Yes; the rip is fine and I've re-ripped several times.
I finally achieved my goal of ripping the disc to the HD for play on our Samsung QLED TV using MakeMKV, which reencoded the DTS audio (unsupported on Samsung TV) to AAC. But would prefer BDRB (it's been awhile since I donated - need to again...) since it is familiar and can output AC3.
Hope this helps:
