Having Trouble with my DVD Writer

I have a Liteon Lightscribe DVDR/RW Optical Disc Drive that I use to burn my files to a DVD.
I only burn around 3 times a month. It was never abused.
My problem now is, I already wasted like ten DVD's in a row while trying to burn a slideshow of pictures I created.
It failed on me like once or thrice before, but ten is insane.
I know Optical drives are cheap, but I'm hoping there's still a fix for this.
I'm using Nero burning software. Anybody got suggestions?
