Hello and welcome to Bleepingcomputer.
DVD burner drives have a shorter life expectancy then we will ever realize.
The reason for this is the laser has to burn hotter then the average CD burner drives ever did, this causes the lasers in DVD burners to burn out quicker than the CD burners ever did. I know we expect better results than that for the price we pay for a DVD burner drive, but that is reality.
I would recommend cleaning the laser lens first, although cleaning disks are supposed to work, they really don't do as good a job as they claim.
The best results can be gained by removing the drive from the computer, opening the drives enclosure, gaining full access to the laser lens, then carefully cleaning the lens with a Q-tip or cotton swab dipped in isopropyl alcohol 70% and gently cleaning the lens.
Re-assemble the drive, put it back in and try using it again.
Please post back the results.
