Media Sharing does not appear as an option in System Preferences

I don't recall ever seeing a "Media sharing" in the File Sharing System Preferences pane -- on my High Sierra system all I have are "File Sharing", "Printer Sharing", "Internet Sharing", "Bluetooth Sharing", "Screen Sharing" and "DVD or CD Sharing" -- is one of these what you are talking about?

Are you using High Sierra or what?? And what exact version? (Do an "About this Mac" from the Apple icon at the top left corner of screen.

Good luck...

AHA, I think you may have it with ... DVD or CD Sharing. :)

Good work, thanks for the report. :)
