The codes were all contributed by volunteers, and sometimes there were mistakes.

I suggest you get the Yamaha Extended codes from their website, turn them into a ccf, even if you have to learn the Pronto programming software enough to do so, then import them with the URC Univeral Browser. Maybe, first, delete the bizarre room and other environment settings that are just plain stupid.

I use ypab (yamaha's dealer website) all the time. Its what I use to make all of my Yamaha templates. It just doesn't make sense to me that the codes are readily avaiable on this website yet the one's in URC's database are wrong or missing.
