Thank you very much Jason, what I meant is, how do you know that function 5 = power? All I get from pronto IR tool is the function number, not the name.

Could you tell me how you know these?

Also how do you know which protocol has which device number? (i.e. xmp = 26.0?)

You've helped me a lot already, I'm definetely going to read the articles at the link you provided. (scanned them a bit already)

Edit: Oh yes, I forgot to mention that the IR Codes work like a charm (I only need to figure out which to use for the functions I want)
