Universal remote (NOTES/WIP).

This probably belongs elsewhere but I want to (un)mute/power(on/off) the tv and the radio from anywhere in the house

Recieving data from the remote

The remote I bought on ebay seems to send 4 different signals per key (in this case the mute key)

The remote that came with the radio is more specific (0x45=KEY_POWER,0x47=KEY_MUTE)

Which is different than the remote for the tv (0x408=KEY_POWER,0x404=KEY_MUTE)
