Hi,
- Are you trying to copy any contents from a DVD to another DVD?
- What type of contents are you trying to copy?
- What type of blank discs are you using to copy the contents?
If you are trying to copy music, pictures, and videos from a CD or DVD to another blank discs, then you may use Windows Media Player on Windows 8.
You need to first copy the contents on the CD or DVD to the computer and then copy to a blank disc.
When you copy music, pictures, and videos from a CD or DVD to your PC, it's called "ripping” and copying music, pictures, and videos from your PC to a blank CD or DVD, is called "burning." You can use Windows Media Player in Windows 8 to do both.
For further information, refer to the articles:
