Burner problem

I currently have a lite on ldw-815s dvd burner. The problem with the burner is that whenever i burn a dvd. The process will complete successfully and then it will not be vberified. It says data verification failed and when i insert the dvd there not be any contents in the dvd, the drive will start to show up as cd drive. i have lost the original software which was shipped with the burner so i used nero 5,6,7 none of them worked, the same problem existed so can anybody hep me please.

I would use better media, eg. TY and Verbatim.
