I've been happily ripping 4Ks for about a year on and off, then recently bought some new ones. Ripped 3 movies fine. Then "The Substance" appeared to rip fine, but playback of the output file broke at about 45 mins in. Then "Deadpool & Wolverine" failed with hash check errors...

Just popping in to say thanks for the guides and resources. WH14NS40 all flashed and ripping with no hassles. I already registered my MakeMKV a month or two back, but now enjoying the UHD side of things
