Or you can do what I did, I had 2 older compaq ipaqs (so I had a spare) I bought "total remote" which is a hardware/software package. It now controls every piece of electronics I own, with an awesome color LED interface, customizable layout and macro support! The hardware mentioned is an IR extender that plugs in the headset jack (weird but works well)
