DVDs and/or Blu-ray movies will not play on Windows 8 or Windows 8.1
Windows 8 and Windows 8.1 don't come with DVD/Blu-ray video playback support built-in.
If you're running Windows 8 or Windows 8.1, you can search for a DVD player app in the Windows Store. If you have Windows 8.1 Pro, you can also buy the Windows 8.1 Media Center Pack that includes DVD playback. If you only have the standard version of Windows 8, you will need to purchase the Windows 8 Pro Pack. Once you have Media Center installed, you will be able to play DVDs — but only in Media Center, not Media Player.
In order to play Blu-ray discs, we recommend installing VLC. VLC is a free, open-source media player that can play un-encrypted Blu-ray discs. There are also many other third-party applications that will allow you to play Blu-ray movies. A quick internet search should provide you with an abundance of options.
Windows RT 8.1 doesn't support DVD/Blu-ray movie playback, and the Media Center Pack isn't available for Windows RT 8.1.
