The only way to add an IR action is to learn it. After learning the IR code or many codes, you then upload the configuration to the RC3200 edit software - and can further configure from there...then download it back. You can link to other learned buttons, but you can't add Custom IR codes. All default devices are pre-programmed with Marantz codes....no other manufacturers codes to pick from. Don't necessarily think you got ripped off because the Philips has other codes built-in. You most likely would learn most of your buttons on the Philips too.
