Never mind -- I fixed it! Turns out that some updates to iTunes make changes to the registry that can mess with the computer's ability to see/access some devices. I simply went to Programs/Features, selected iTunes and clicked Repair. That took 10 seconds and after that, my computer is now able to access my DVD drives.

Fix Code 19 by "repairing" iTunes
What worked for me-
Running Windows 7 Home Premium.
In "Programs and Features" right click iTunes and click "Repair". After completion, CD and DVD devices should appear in Device Manager with no conflicts. After finishing, if problem was fixed, go to "Computer", right click, then left click "System Protection" and "Create" your own "System Restore Point", in case this ever happens again.
