The iTunes software, pre-installed on all Mac computers and available for free for Windows-based computers, is more than just a music management program. It also connects you to the online iTunes Store, where you can download millions of songs and videos. Though most of the videos cost money, the iTunes Store periodically offers free video clips and movies.
Launch the iTunes software from your Windows "Start" menu or from inside your Mac's Applications folder.
Click "iTunes Store" in the left column of the program. The online store will appear in iTunes' main window.
Press "Music" in the black menu bar at the top of the iTunes Store.
Click "Free on iTunes" in the right column. A list of all the current free media will appear.
Select any video title to view its description and download it. Download times for a 45 minute video on a broadband connection range from three to 20 minutes, according to Apple.
Connect your iPod or iPhone to your computer using its included USB syncing cable. The wide and thin end goes into the bottom of the device, and the standard USB end plugs into any available USB port on your computer. The iTunes software will automatically transfer the video you downloaded onto the device so you can watch it anywhere you want.
