You will need a USB cable, a large enough video stick for your PSP to hold your video, and the video must be in mp4 standard. Turn off your PSP, connect the USB cable from your PSP to your computer. Turn on the PSP. Windows will create a removable drive shadow in ‘My Computer’ of your PSP memory stick. Click on the PSP icon in ‘My Computer’, and create a folder called ‘MP_ROOT’ if it’s not already created. Click on ‘MP_ROOT’ and create another folder called ‘100MNV01′ if it’s not already created. Copy your mp4 video files to the ‘/MP_ROOT/100MNV01′ folder. On your PSP goto VIDEO, select MEMORY STICK, and you will be able to watch videos on your PSP.
