Is my New Sony DRU 830A DV Writer Bad?

I am trying to write only 2.93 Gb of Video Files on DVD -RW using my Sony DRU 830A. I have tried Nero 7 No good.Now I tried Freee Easy CD DVD Burnver V 1.2 and it just gave me the “Logical Block Address Out of Range” after 57% of the data was written and it ejected the DVD. It passed the Nero Drive tests for read and write very well.It can write smaller files well.The media is good as I filled it with over 4 Gb of data using my office DVD writer, easily.

Is my One month old burner BAD? Please reply very soon.I am stuck.
