FWIW - The RR2150 is so simple relatively speaking compared to a HT receiver and so few functions are used after the initial setup that its easy to use a learning remote. I setup a Mx-500 using nothing but learned buttons for a Toshiba TV, the RR2150 and a Squeezebox fairly quickly. I think the whole thing including macros took less than 2 hours with the majority of time removing the defaults from each screen.
