Sony dru810a burning problem

I am having a problem burning now. I burned about 10 dvd+r dl’s fine. Then it started burning the first layer and would bring up an error on the second layer. So I restored my whole computer. Now When I use nero recode it will save image to my documents, but wont ask for blank media when it is finished making the image. I am at my witts end here. DOn’t know what else to do.

Is there a log(file) you could post?
