How to burn a dvd with a one drive computer by emachines

Do you have a DVD-ROM drive or a DVD±R/RW drive?

A DVD-ROM drive will only read DVDs but not allow you to burn them.

If you indeed have a DVD±R/RW drive you should be able to burn a DVD.

Are you getting some kind of error message when you are attempting to burn a DVD?

BTW, Cyberlink is generally for watching BDs/DVDs. Most Windows users use Nero or Roxio for their DVD burning software. What Cyberlink product do you have for burning DVDs?
