PENG has to be in advanced mode (an option available during startup or as an option of the File menu; may require a restart of PENG). Then you can press the View/Edit button under Add IR Code and paste in your discrete codes. Believe me: this one frustrated the heck out of me until I figured out the Advanced Mode option. I know there have been a couple of other related posts in this forum...just can't seem to locate them at the moment. :-)
