More weirdness! Googling around I found some suggestions to see if the 
low level scan and key codes for the Hauppauge remote are being seen and 
what they are. These tools included xev which can be ran from an X11 
terminal and showkey -s  and showkey -k run from a tty console. While 
each of these show more responses to button presses on the remote, than 
I had seen with IRCAT or IRW , none of the three versions showed the 
same set of keys being seen! And none showed responses for all the keys. 
For example the channel up button would show a response for showkey -k 
but not for showkey -s or xev! Go figure!
