Disk or Disks? If it's the same disk giving you problems, it might have already been burned. You get re-burn DVD-/+R, you get with a DVD-/+RW.
If it a bunch of disks and every one is giving you that error, then that bran of disk will not work with the drive in your computer. You may have to try another brand. Which one you ask? Got me, it just trial and error on that part. I use TDK and HP and not having had any problems with them.
