plug in your psp, and set it to usb.
start up psp video 9.
confirm the location of your psp (its drive letter)
go to convert and select the video you want converting.
select the resolution and sound quality in the drop down menu and convert your video.
then go to convert... if the video desn't appear to be there, there is a little menu on the left pane that you should change, then on the right pane select the same option you did in the left and then send the video.
its really easy to use, it doesn't take long to figure it out
