The Slysoft solution is to use Clonecd for Verbatim+R DL. Just open Clonecd with Anydvd running the background and click a couple of times. No need to rip first before using Clonecd or switch to another program.
But an error message, at the very least, would be nice (in addition to the other information I'm asking for).
I agree that the 50% area would suggest a layer break problem or a disk size issue.
Presuming joelnchristine is using Clonedvd2 and a single layer blank (4.7GB), ensure "dvd-5" is selected in Clonedvd2.
