I'm using the latest MakeMKV version 1.18.3 on Windows 11 25H2. My PC has two Bluray drives installed (one Asus BW 16D1Ht and one LG WH 16NS55 with firmware 16NS60). I also have an LG WH 16NS40 with firmware 16NS60 connected via USB.
Recently, I tried to back up three Blu-ray discs simultaneously, as I've done successfully many times before. In this case, two were UHD and one was a standard Blu-ray.
Unfortunately, I found that the backup process took much longer than I've ever experienced before. Each disc took about 1.5 to 2 hours, simultaneously, but incredibly slowly. What was particularly noticeable was that each drive would be reading from the discs and then suddenly stop. After several seconds, it would start reading again, stop, and so on, until the discs were finished.
Has anyone else ever experienced this phenomenon
