IRON MAN 3 errors out

[prodigymex]

I got the following error:

Error 'OS error - (ipc/send) invalid destination port' occurred while reading '/BDMV/STREAM/00912.m2ts' at offset '2359296'
Backup failed

Besides when MKV opens up it doesn't show me the titles in the disc so I can select them it will only give me the option to backup the entire disc. Why is that?
thanks

Do you mean the big button with the disk on it is greyed out, so you can't click on it?

I think this is the same problem I am having. Forgot to copy the error and trying to back it up again now.

Most annoying part is it errored on the very end of the backup.
