DVD driver not reading DVD but reading cds?

Are you certain that it's a DVD drive? If you only have a CD drive it won't read DVD's, and you'll need to upgrade to a DVD drive. If it's more than a couple years old it's probably a CD drive.

To find out, open the "Device Manager" on your computer, then DVD/CD-ROM drives, then expand your CD/DVD. (select the little + to the left)

Click "properties" then examine the tabs across the top.

If there are 5 tabs they probably say something like "General", "Properties", "Volumes", "Driver", "Details". If that's what it says, you have a CD-Drive and it won't read DVD's.

On the other hand, if you have an additional tab that says "DVD Region", it's a DVD drive and it should be able to read DVD's.
