OS X Catalina: DVD player "not supported" for external DVD Drive
I tried an LG external DVD-RW drive. It saw the DVD disc ("Scrubs" TV show, Season 5 disc 3) in the Finder, launched DVD player. which showed the error message "Not Supported," then the player crashed. I restarted, and got the same result. Being in a very customer friendly store, I opened an Apple USB SuperDrive and tried that. Same result. Have used the LG drive with High Sierra flawlessly. Have tried other DVD discs. I think it's a Catalina problem.
