When you first open Dragon Player a pop-up window asks what you would like to Play File or Play Disc. If you choose one of these the program loads the file. You can also Close the window or Quit the application.
Selecting Play > Play Media allows you to play a DVD, VCD, or Video File, Play/Pause lets you pause and re-start the movie, Stop will stop the playback, and Quit closes the application.
The Settings menu lets you choose the Full Screen Mode, Aspect Ratio, Subtitles, Audio Channels, to Configure Shortcuts and Toolbars or to Show Toolbar.
Help > Dragon Player Handbook, or pressing the F1 key, opens the manual.
