Solution Found
The drivers for the CD/DVD burners were corrupted by possible one of the burning and/or video editing programs I installed. Attempts to uninstall both the drivers and software failed. The solution was to make an edit in the registry. After being directed to the correct section I was mistakenly trying to delete the whole section, which the OS would not allow. I then learned that I only needed to delete a single line (of possibly 2) to make the correction. In RegEdit.exe take this path; My Computer; HKEY_LOCAL_MACHINE; SYSTEM; Control; Class; {4D36E965-E325-11CE-BFC1-08002BE10318}. Confirm that right pane contains several lines including referrences to CD/DVD Drive. Click on UpperFilters line, right click delete. Click on LowerFilters line, right click delete (both lines may not exist, delete only one if only one is displayed). Close RegEdit & reboot. This corrected the problem on my system and all optical drives were displayed in Device Manager as working properly.
