DVD drive detected but not reading

I'm running Ubuntu 20.04 and recently tried to use my DVD drive. It worked on 18.04, and I hadn't tried it after upgrading until now. The unit works in another machine just fine.

I can see the drive in the Disks application, but nothing happens when I put media in. Most issues I've seen from Google searches seem to be errors reading rather than no reading.

Any help would be appreciated.

Thanks in advance!
