As with other Mac OS X applications, the settings that dictate how the application functions are stored in an area called Preferences. To see or alter the DVD Player settings:
- Launch DVD Player
- Click on DVD Player in the Menu Bar
- Choose Preferences

As you can see, there is a heading on the top that has settings for the features within DVD Player. Simply make changes as you see fit for:
- Player
- Disc Setup
- Full Screen
- Windows
- Previously Viewed
- High Definition (HD)
