Norton IS2010 causes DVD creation to fail

I have NIS2010 installed. Whenever I try to write a DVD, the write fails and I can attribute the failure to Norton. For example, I look and there was a Live update that ran when the failure occurred.

 

I need desparately to know how to temporarily stop Norton from taking any action while I am writing the DVD. I myself do not do anything while the burner is in operation.

 

It is maddening to find that 15 to 30 minutes was just wasted because of Norton.

 

How can I temporarily quiet Norton?
