Well, I've downloaded both those programs, but I'm not much further forward.

Firstly, MakeHex won't open no matter how many times I double click on it. The readme file suggests that it might not be a conventional Windows program and may need running from the command line. However, the description is just double-dutch to me.

Secondly, IRpanels seems to be expecting me to already know the codes before it will do anything. The online description of IRpanels suggests that it is a companion program for ProntoUtil, which I also downloaded. However, ProntoUtil assumes a great deal more knowledge about IR technology than I possess (i.e. absolutely none).

I'm sorry to be a pain, but without step by step guidance in plain English I'm not going to make any progress.
