Is this the remote with only a few buttons and voice command? It might be easier to buy a Harmony 650 and teach the commands to the remote you want to use. BB has them for $69 and if you have a Skywalker account, they sell Harmony now, too. IIRC, you're in PHX and they recently opened a branch there (South of I-10).
