If you are interested in a single button, put your IR actions into the ActionList, then put this into your script and then make sure that in PEP2, the ProntoScript and not the ActionList is showing.

sendCommand("Stop()");
sendCommand("ClearPlayList(0)");
refreshPlaylist();
try {
// within a button, 'this' refers to the button.
this.executeActions();
}catch(e) {
// ignore actionlist error
}
