I am trying to make a backup copy of my DVD Iron Man 2 (I live in a country where it is OK).
This particular DVD has special tricks to prevent buyers from doing that (see dicussion for Mac).
I wanted to create an ISO file but dd does not work:
$ dd if=/dev/dvd of=ironman2_backup.iso
dd: error reading ‘/dev/dvd’: Input/output error
12192+0 records in
12192+0 records out
6242304 bytes (6.2 MB) copied, 2.92969 s, 2.1 MB/s
I tried ripping it with Handbrake several times, but somehow the resulting MPG4 files either do not have any sound, or show only a fragment of the movie, like the intro.
QUESTION: How to backup this particular DVD?
