This is what DVD Identifier gave me when I clicked "Identify" and "Clipboard":
Unique Disc Identifier : [DVD+R:CMC MAG-M01-000]
Disc & Book Type : [DVD+R] - [DVD+R]
Manufacturer Name : [CMC Magnetics Corp.]

Blank Disc Capacity : [2,295,104 Sectors = 4.70 GB (4.38 GiB)]

The DVD's I'm using are TDK 4.7GB DVD+R 1-16x. I am using them to burn and store various video files to free up my hard drive space.
Here is a screenshot of another PI/PO test. Not sure what all this even means. It stopped when it received that error again.
