I am maybe blind.
These are the files that i can download.

BTW this is in refference to :
4. How Do You Use IR.exe
This is the program that you use to communicate with your remote. You can use it to download your current programming, you can save a copy of your current programming on your PC as a backup, you can make changes to the programming, including adding upgrades, etc and you can re-load it to your remote.
First, download the program IR.exe from the Tools folder. Unzip the contents of the file into a folder on your PC. Next download the current set of RDFs, also from the Tools folder and unzip these into a separate folder. Finally, you will need to establish a link between the RDFs and IR.exe. To do this, fire up IR.exe and select File > Set RDF Path, this will bring up a standard Windows pop-up screen where you can select the folder you created for the RDFs. You will also need to download the DecodeIR.dll program, which you can either store in the same directory as IR.exe, or better yet, you should store in your Windows / System directory as it is used by several other JP1 programs.
I am new to all of this and before noon today i didnt really even think reprogramming IR devices, but upon opening a brand new ipod and then reading about the gadgets that you can get/build for it i discovered the IRIpodHack. Upon reading about that I found this, anyways I am very interested in learning how to reprogram remote controls and consider it a new project.
If someone wouldnt mind answering a few learner/noobish questions I was wondering:
Is it possible to capture a IR frequency? I mean because it would be useful to know what frequency some things work on, so i can make a interface for all the equipment in my house. For example one to open my garage door, then once inside turn on music and tv... Am I looking at it from the wrong angle? I'm quite lost but I've been doing about 6 hours worth of reading today and I'm going to buy a 6Pin Universal Remote when the shops open and then buy some Jp1 cable. (Or I might make it, depends how available the components are).
