Instructions
Insert a memory stick into the PSP's memory stick compartment while the unit is turned off, then turn it back on by sliding the power switch up.
Attach the PSP's USB cable to the PSP and your computer's USB port.
Scroll to the left on the PSP and select "USB Connection" from under the "Settings" menu to establish the connection.
Click "Open Folder to View Files" on your computer as it recognizes the connected USB device.
Open the "VIDEO" folder by double clicking it. If there is not a "VIDEO" folder on your PSP memory stick, click "Create New Folder" from the left side of the open window and name the new folder "VIDEO."
Open the folder on your computer holding your PSP movies.
Drag and drop the PSP movies into the "VIDEO" folder. As soon as you drop the files into the folder, the computer will begin transferring them to the PSP's memory stick. You can now access the PSP movies from under the "Video" tab on your PSP's main menu.
