Being a reader on this forum for quite some time, I finally decided to join to try to help out with subjects where I might have knowledge or new ideas.
Regarding the option programming, the IR strength is limited and you have to be right in front of the product that you want to change to option for. It is made this way to prohibit that you by accident sets the option for all your products within IR range. The IR range (when limited) is approximately 1 meter (3 feets) so you have to be quite close to the IR receiver of the product.
Please try to see if this works. The product gives you a feedback by flashing the red diode if successful.
