Basically, on this disc, there are 7 episodes and a bunch of extras. Don't care about the extras, just the episodes. What happens is with makemkv, it reads the disc, no errors, but it only detects 4 titles, 3 of the episodes and one of the extras. These read and rip just fine, but makemkv doesn't see the other 4 titles at all. In handbrake, it sees all the titles, but seemingly can't read them. But the disc does play back fine on a DVD player or in VLC. I've tried multiple drives with the same results in each case. Logs are below, not sure how to troubleshoot this further without sending a disk to Mike
Oh, and as an aside, there's still a long-standing bug where makemkvcon on linux refuses to backup a disc because it thinks an empty folder isn't empty:$ makemkvcon info disc:0
