Well, if it just started happening while using lightscribe, I would have to assume the laser is probably bad now. A new DVD burner combo drive will only set you back $30.
The only thing I can think of is going to control panel, system, hardware tab, and go to device manager. When device manager opens, go under optical drives, right click on the DVD drive and click uninstall. This will uninstall it, and it should ask if you would like to restart, say yes. When your computer boots back up, Windows should automatically reinstall the drivers. See if it works any better now.
