GSA-H54N Problem

This is my first post.

I just got the LG GSA-H54N burner and I am having a problem. When burning a DVD in any program the drive crashes at 75% of the finalization of the disc???. This appears to be the only problem as it is reading discs fine. I am using verbatim dvd-r as a medium, and making some coaster out of them along the way. Any suggestions would be appreciated.

Thanks.

What burning program have you used?
