First, check if this DVD is indeed a blank one, just open the explore of windows to browser it.
If indeed blank, try another DVD burn software, sometimes the burner is not well compatibled with the blank discs. I suggest you have a try with Longo DVD Copy from
http://www.longodvd.com .
If still failed, maybe some problems with this blank discs, I'm afraid you need to exchange it for another one.
