How to Play an HD DVD in Windows Media Playerby Richard Schupp
High-Definition DVDs were in direct competition with Blu-ray discs as the next generation of physical video media. Blu-ray has since won the battle for consumer appeal, but some people still own HD DVD players and computers with HD DVD drives. Windows Media Player is capable of HD DVD playback: So as long as you have an HD DVD drive in your computer, you will be able to play the disc through Windows Media Player.
Make sure your computer has an HD DVD drive. You can check this by clicking the "Start" button, then "Control Panel," then "System and Maintenance," and then "Device Manager."
Click the arrow next to CD/DVD drives, and an HD DVD drive should show up.
Insert an HD DVD into your computer's disc drive.
Click the option to play the disc in Windows Media Player, and the HD DVD will load in Windows Media Player.
