When I have Media Center open and put a CD in a drive, I have a window that pops up with the info that has been found in the online database. If you are not seeing this window, you should check your firewall (Windows Firewall, etc.) to confirm that Media Center appears in the list of permitted applications. Assuming that you are on Windows 10 and using Windows Firewall, I go to Control Panel\System and Security\Windows Firewall\Allowed apps to see the list. I believe that the Media Center install asks if you want to allow it to create an exception in Windows Firewall but you can manually add it from Control Panel. Once you have done so, I would close Media Center, remove the CD, reopen Media Center then put the CD back. It should then access the online database (at least it does for me).
