I have tried 3 DVDs and all give me the failed verification.  They say that they burn successfully, but the verification of the disk fails.

I bought Verbatim DVD+R disks.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
