Hi,
Please go to control panel\all control panel items\troubleshooting to check if it is available to find and fix media player DVD automatically.
Go to Device Manager, uninstall the existing DVD driver, then reboot computer again to load a new driver to check the issue. Or we could go to manufacturer website and download the latest system compatibility version for checking again.
Try to insert a new DVD to check if it prompt for asks. If you could get any other external DVD player, try to check if the issue related with hardware.
Bests,
