Problems with Nero express

[intersat]

When i burn a backup dvd with Nero Express, i get in the final stage of the burningprocess a message"could not perform end of disc at once".
When i put my dvd in my dvd player it works so why bother......
When i try to make a copy of the backup dvd, dvd shrink and nero can not read the dvd.
How can i make the error go away.

Run Nero Burning Rom and set it to track at once.

Perhaps there aren't all the files in the backup.Dvd Shrink needs all files to work properly.You can give me the list of the files you have in your backup up to help you better.
