I am setting up a new RCA HD television and am trying to find discrete codes for switching inputs and for power on/off.

FYI, I'm pretty sure the TV has discrete control, since the provided remote can automatically switch inputs depending on which device button is pushed. (I realize I could use that to learn the switching commands, but unhappily the system don't allow access to all the inputs, just a subset.)

Anyone have any info?

Thanks in advance.
