Mac OS X comes with the tools you need to play movies and digital video, including the DVD Player and QuickTime Player applications.
If you have Apple's iLife suite installed on your Mac, you can also create your own digital video movies. Using the iMovie application that comes with the iLife suite, you can import camcorder video to your Mac and use that video as the raw footage for your movie. With iMovie you can then apply scene transitions, and add titles, credits, and a soundtrack.
