Hmmm, I need to dig mine out again... I got it when I had Time Warner and their SA8300HD set-top but they had stupid-a** "A", "B", and "C" function buttons that were a pain to 'map' on a remote.
You can e-mail their support dept, tell them what remote you have, and what device you're trying to control and they can give you additional codes. Also, try
RC Forums: One For All & Radio Shack Index for help too.
