What I am reporting appears to be entirely reproducible on certain sets, and has only started happening in the last month or two.
I've been using MakeMKV for several years now. It has always worked fairly flawlessly for me. I have never before suspected that MakeMKV was the culprit of an unreadable disc, rather than simply damaged discs.
But in the last month or two, I've run into 3 separate sets where:
1) A disc in media that I buy on ebay proves unreadable.
2) I am either sent or purchase an identical copy of that set.
3) The replacement disc fails *in the exact same place on the disc*, which seems to me to be exceedingly unlikely.
Examples:
1) Que Pasa USA (old bilingual TV series): Both copies of Disc 2 fail at output size 3698.6M. Exactly the same spot.
2) Dark (German sci fi series), Blu Ray - both season 3 disc 2 copies I have fail the same place, near the end of the last episode.,
3) Counterpart (Starz scifi series), Blu Ray - both season 2 disc 2 copies fail at the same place, near the end of the last episode.
As I said, never experienced this until recently. Encounter it on multiple optical drives (pioneers), and on both Windows and Linux. It doesn't happen on every disc I try to rip, but pretty much anytime I encounter an error now, getting a replacement is pointless as it will fail in the same spot.
I have enough years of trouble free use of this software that I am suspecting a regression in a recent version. Any help (or just taking this report seriously) would be greatly appreciated. I was already planning on finally buying a permanent license, but any attempt to help will absolutely guarantee it.
Thanks again for this great and invaluable software.
