Copy the movie ISO into The Video subfolder of the ISO folder on your PSP memory card . If there is not one just create it in caps .
Once you get it copied Press SELECT to bring up the "VSH MENU".
Go down to "ISO VIDEO MOUNT NONE", press left or right on the D-pad. You should see you video's name where it says "NONE", then go down to "EXIT" and press X.
YOU MUST HAVE A UMD IN THE DRIVE , IT CAN BE ANYTHING GAME OR MOVIE...
That should do it.
