Just right click on a button, choose edit properties,
click infrared tab and turn frequency to 0. Or better
yet open the Library Manager, open the Sony 777 es remote
file, duplicate it with a new name and then modify all
of the carrier frequencies. That will make it easier
each time you need to do this.

I always love the term "strip the code", not to be mean,
I remember way back when when other audio professionals
would use this term just to make me feel stupid and that
I could never understand this. I just tell others that
all you need to do is turn the carrier freq to zero.

We all have to start somewhere.
