Comment 18 for bug 72872

This problem has also bugged me, albeit on Debian. And I spent an hour or two to do it "the right way" and get UDF (in that case) to ignore the permissions on the filesystem.

After playing with mount options to no avail, I finally gave up and became root to get the discs content copied.

I think it really sucks to enter an optical disc and be unable to read it because of permission problems. There should be a mount option to ignore permissions for udf and iso9660 and this should be enabled per default in fstab. The thing is: This will probably need kernel changes...
