Instructions
Power on your PSP and then navigate to the PlayStation network on the right side of the main menu. Press the "X" button and log in to your PlayStation Network Account. If you have not yet set up a PlayStation Network account, you will be prompted to enter some basic details (such as email address and name) to create an account.
Select the PlayStation Store from the sub-menu and then navigate to the "Videos" tab. Use the directional buttons to select the search box at the top of the screen. Then type in "Superhero Movie" followed by the "Start" button.
Press either "Rent" or "Buy." When you rent a movie, it will be less expensive (around $3) than buying and will be available to watch for three days. If you buy the movie, it will be available on your PSP as long as you have it. Once you have made your choice, the movie file begins downloading immediately.
Press the "Circle" button to exit the PlayStation Store. Then navigate to the "Videos" tab on your home screen. You see a "Superhero Movie" icon.
