Help with remote control amplifier

Hi,
I have a small project that Im working at. I want to amplify an IR remote control (dvd, TV, Air conditioner...)
I found this one on dealextreme:

I was wondering if I can just replace this item with the original IR-LED, or that I have to modifiy something.

Many thanks

When I click your link it says bad request. And no matter what diode you swap into it, the remote will still be outputting the same amount of power

Sorry, here is the emmiter :
0.5W IR LED Emitter on 20mm Board - Free Shipping - DealExtreme

so... how do i use it with my remote if the new diode needs more power ?
