i have a question

can you plug-in a ps2's video to a psp somehow?

no, you have to buy a special adapter made by sony or other 3rd party companies, in the pic, it shows a model example

Do you mean get a PS2 to output video onto the PSP screen? There was a complicated Component hack that I saw done but there isn't anything off the shelf that can do that.
