I saw something called a mutedaddy that mutes the tv when you press the button and unmutes after 2 minutes. I realise you have to get the right infrared code to make it work, can i program it with my remote’s ‘back’ button, as this button switches between my current channel and the last channel i watched. if not, is there some other device that could do a similar thing? I just don’t want to sit in silence, that’s all.

Thanks!
