The problem turned out to be an applications error. I was trying to access the
DVD burner from Pinnacle's Studio (version 9) software. Somehow, after doing
a recommended update, the program could not address the burner. After uninstalling and re-installing the program without the update, the installation came up with a magic key code, which I was able to use to access the the web
for downloading software to make the connection with the burner. This magic
key code is not explained anywheres in the Studio documentation. Everything
is working fine now.
