Can't make an iso of burned DVD-R

I've got problem while trying to open burned DVD-R, I even can't to make an iso image of it within dd - after making iso image, I've tried to mount them:

mount -t iso9660 /dev/cdrom /mnt -o loop=/dev/loop0 
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
     missing codepage or helper program, or other error
     In some cases useful info is found in syslog - try
     dmesg | tail or so.

But when I open the DVD on the windows it works perfectly. I've tried to make an iso image there but get a lot of errors ( Alcohol 120% ).

Is it some sort of copy protection? If yes, how it works? I can easily open it in windows, but can't to make an iso image of it?

May be I'm using wrong software for making iso images, any suggestions?

The DVD contents software, not audio or movies.

Solution

I don't understand what you are trying to do, dev/cdrom is not an image, its the drive. What command did you use to make the image? Anyway, assuming you ran something like

dd if=/dev/cdrom of=/tmp/image.iso

You can then mount it like so:

mkdir foo
mount -t iso9660 -o loop /tmp/image.iso foo/

If this does not work, your image file probably has problems. Alternatives for creating the image are to use programs like brasero or k3b or mkisofs:

mount /dev/cdrom /media/cdrom
mkisofs -o /tmp/image.iso -graft-points -rational-rock -full-iso9660-filenames -iso-level 2 -r -J /media/cdrom
