The iTunes Store is the best way for iOS, Mac and PC users to legally discover, purchase and download music and video online. iTunes is the world's most popular mediaplayer for Mac and PC.
To play back video, you can either pop the SD card out of the clock and into your PC or connect the clock to your PC via an included USB cable. (Unfortunately, the cover for the USB port fits poorly.) Video files can be played by Windows MediaPlayer on the PC or QuickTime on either the PC or Mac after adding the DivX component.
