The only problem I had was the up-arrow key - my remote  (Home Theatre 
Master 8000) says it learned it ok, but it seems to send many with one 
keypress? Or I think more likely the key-up code was corrupted? - 
because the keyboard does the same thing occasionally with any key if it 
loses good sight of the receiver. I tried learning it a half dozen times 
with the same result. The other arrow keys work great.
