A DVD drive is something entirely different. It should read fine. Unless... you don't actually have a DVD drive.
There's no such thing as a CD-rom that can read DVD. You can have a DVD read CD, because of downward compatibility, but not the other way around.
So which is it? Do you have a CD-ROM or do you have a DVD-Rom?
