Ok i've just started putting different things on my psp. I have the usb cable and i've figured out how to put photos onto my psp. But when it comes to videos and music i'm clueless. I have a few music videos i want on there and they're in mpeg-4 but when i try to put them on there it just takes space off my memory stick and no videos are to be found. same with music. i guess im not creating the right files for it. can anyone help with this. and i know there's a media manager but i've been told you don't need it.
