[ubuntu] DVD Not working

Greetings,

Currently experiencing issues with my DVD, which was previously working. Not sure when or why it ceased working, as I do not use it often. Seems that the system recognizes it as indicated below.

OS Ubuntu 16.04

Have tried multiple Video and Audio CDs that work in other devices. Appreciate any assistance in resolving this issue. Thank you in advance.
