Q: i already went to mediaconverter.com but when i choose to make a youtube video into a "psp" file, it is unknown. i want to know an other alternative to take, so i can play youtube videos on my psp
A: The format has to be MP4 and you will probably want to put it in the VIDEO folder. Check the official info here - http://www.us.playstation.com/Support/PSP/Movies/default.html
