I am not sure how your specific application demands something different from standard HDMI passthrough which is usually automatic requiring no buttons or menus. I do not have an 80.3 but every other recent prepro, so far, does this without any programming at all.
Still, if this function is critical for you and you are happy that the 80.3 meets your needs, I see no reason to deter you.
