Iron Man - Can't Backup

[berlin1525]

Hello,

I'm receiving the following from the log when I try to backup Iron Man on Blu-ray using MakeMKV on Mac 10.7.2:

Saving 1 titles into directory /Users/berlin1525/Desktop/Iron Man

LIBMKV_TRACE: Exception: Error while reading input
Failed to save title 0 to file /Users/berlin1525/Desktop/Iron Man/title00.mkv
0 titles saved, 1 failed

I tried returning and getting another disc since I was receiving similar errors before. Do I need to send it back again? I was able to backup Iron Man 2 with no problems. I just upgraded to the latest version of MakeMKV to see if it was resolved but it isn't. Any ideas?

Thanks in advance!

The error is telling you the drive is unable to read the disc. You may wish to try cleaning the disk with a soft cloth (such as you would use on spectacle lens'). If that fails then return it for a new disc.
