this is perfect software for converting to PSP format:
first go to google and type in SUPER. then click the first site that comes up. scroll all the way down to the end of the page and it should say Start Downloading SUPER ©. click that and it will bring you to another page that looked similar to the last one. scroll down a little bit until you see download and use in blue letters. it should be in the red printed paragraph. then scroll all the way down and you will see Download SUPER © setup file. click that and your set. when its finished downloading just open the installer.
it converts nearly ANY file to PSP. it is great with movies. i've converted hundreds of movies and they have turned out great.
