Burn Process Failed (Uploaded log.txt!)

Hey,

I have a fairly new version of Nero and am using Nero Express to make a duplicate of a disk that I burnt. I have to make around 200 of them. I am using my external brand new Sony burner but it gives me an error at the end. Attached is my log.txt.

I could really appreciate any help you can pass along my way!

Thanks a lot,

Chase S.
