Windows Media Player in Windows 8 or later does not support DVD video discs. You need to pay to upgrade Windows Media Center.
If you need to play DVD on Windows 8 or later, we suggest installing a free Third-Party DVD Player, such as K-Lite, KMplayer and VLC media play, to support DVD video discs.
Please refer to the following Microsoft website for more information:
