How can i save a movie on my psp memory card? please help with good step by step instructions.or just help?

Answer 1

If it is already an MP4 file...
Just plug in the USB cable between computer and PSP.
The computer should see a new "drive."
Assuming the drive is E:, then you copy the MP4 file to E:\MP_Root\100MNV01

Otherwise you may need to convert it to MP4 first.
Here is a way to do that:
