The burned disc can not be read on a player.
Please try the steps:
1. Please make sure that your DVD burner supports the DVD±R/RW disc you use.
2. Please select 4x or 1x as the burn speed in the "Advanced setup" window and use 4x namebrand DVD±R/RW discs, such as Memorex, Fujifilm, or Verbatim for example.
3. If you use a DVD±R/RW disc, please format it before burning.
4. Please select your target hard disk and back up your DVD on your hard disk. Then you may burn from HDD to the DVD±R/RW disc with Nero Burning ROM or Roxio Easy CD & DVD Burning..
