Oddly, when I tried to select C2D, the Disc Copier window abruptly closed. So there's something else going on besides the source disk.
I was able to achieve a work around. I had access to a laptop loaded with EMC 9. I saved the disk in ISO format using EMC 9 and then transferred it to the computer with the DVD burner. Then using the same offending EMC 7 program I was able to burn the ISO file to a disk.
