I have only had a few blurays that won't rip, but it is a bit annoying when they won't. Overall makemkv is great though. Here is the error I get:

LG bluray drive and a pretty fast computer. I have backed up most of our bluray collection, but have a few that aren't working. Thanks!

I was on 1.8.2 and I upgraded to 1.8.3 and it still doesn't work.

MEDIUM ERROR:L-EC UNCORRECTABLE ERROR'

Dirty or damaged disc. Try cleaning. If still NG, exchange at place of purchase...

I thought the same, but the disks looked perfect. On X-men 2 I tried 3 different disks and none of them worked. It seems like some sort of coding or formatting with the disk. All of the disks seem to be of a similar age too except for Boondock Saints II. Nemo, the incredibles and X-men 2 are all made within a year of each other and they are the only other disks I have had an issue with.

Unless your eyes can see all the 1's and 0's that make up 50gb of data, you can't tell by looking what the quality of the disc is.

The error message is telling you that your drive can't read the disc. If you don't want to believe that the disc is bad then you need to buy a new drive.

I believe it is the drive. I tried to copy the file manually (not in .mkv format) and it got stuck 249.7MB in to the file also. I got X-men 2 ripped, but from a DVD we had upstairs.
