I am able to download some of the custom ccf files off this website. I used the one by Ian Duncan "Apple OS-MX". I need to change the Direct Tv button to be a Dish Networks button. I need the XM button to be a sirius button. Ian gives a blank button at the back of the configuration, however, I don't know where to get the overlay to put the dish network logo on the blank button and how to edit it in my software, Paint shop pro 9.
