Is the DVD burner dual format? Most likely it is. Have you tried to burn DVD+R discs?
I'm not sure what dual format is, but its records dual layer DVD-Rs. I haven't tried DVD+R discs, I don't see why it should matter since this drive is capable of burning with both DVD-R and DVD+R discs. Do I need some sort of burning software or can't I just use WindowsXP SP3 to burn DVD-Rs? I'm a bit reluctant to spend more money just for trouble shooting, I've already spent the money ($30) on the first DVD-R burner and now again $30 on the second burner. I'm not throwing one more penny into this black hole!Have this drive. http://www.newegg.com/Product/Product.aspx?Item=N82E16827135204
