Instructions
Turn on your PSP, insert your PSP UMD disc, and press the "Select" button on the PSP. Go down to the USB Mode and change it to UMD ISO. Press "Select" once again to exit.
Connect your PSP to your computer with the supplied USB cable. Once connected, your PSP will automatically go into USB mode, and a window will pop up on your computer, giving you access to the PSP's UMD disc.
Copy the UMD ISO file onto your computer and disconnect your PSP from the computer. Press "Select" and change the UMD Mode back to "Memory Stick." Remove your UMD from the PSP and reconnect the PSP to the computer.
Copy the ISO file you placed onto the computer into the ISO/VIDEO folder on your PSP. Wait for it to transfer and disconnect your PSP from the computer. Navigate through the PSP menu until you find the movie and select it to play.
