Watching Movies with DVD Player in OS X Mavericks
The DVD Player application in OS X Mavericks includes snazzy little on-screen controllers. They enable you to watch your movies on your Mac in pretty much the same way you'd watch them on your TV with your DVD player.
Follow these steps to watch a DVD on your Mac:
Insert a video DVD into your optical media drive.
This step automatically launches the DVD Player application; if it doesn't, you can double-click the DVD Player icon in the Applications folder or single-click it in Launchpad to start it.
Use the controls to play, stop, or pause your DVD and more.
The controls themselves should be self-explanatory to anyone who has ever used a set-top DVD player. If they're not familiar to you, hover the cursor over any control to reveal a tooltip. This works for buttons on either type of controller.
Use the Controller drawer if you like to give DVD Player less commonly used, but still useful, commands.
To open or close the little Controller drawer, choose Controls→Open/Close Control Drawer, press Command+], or click the little pull tab (where you see the arrow cursors ) and drag.
The controller might disappear after a few seconds. To make it reappear, jiggle the mouse or choose Window→Show Controller (shortcut Command+Option+C).
If you're in Full Screen mode, the menu bar won't appear unless you move the cursor to the top of the screen. Doing so also makes the chapters/bookmarks/video clips overlay — which you use to choose a chapter, bookmark, or clip — appear just below the menu bar.
So move the cursor to the top of the screen to see the menu bar and chapters/bookmarks/video clips overlay, and move it to the bottom of the screen to see the transparent controller.
Sit back and enjoy the inserted DVD movie on your Mac screen.
