once you have iR Shell on your psp, download the 2000 code pack thing and put it on your psp. then open iR Shell up and move over to the 'iR Remote View' and click on 'codes or 'discrete codes' to find a product you want to control. then once you find it, click on it and a list of commands will pop up telling you what the buttons do. then you point the top part of teh psp towards the objext and press the buttons.
