Finally found some time to do some testing with this. 

I ran evtest and found the remote is not producing any extra key presses, it 
functions as you would expect. So I then tried running irw from the lirc 
package again and found it to be working as expected, which I couldn't 
understand. Then I loaded up mythtv and tried using the remote to navigate 
around the menus - with very annoying behaviour, the menus would jump around 
unexpectedly as though an extra key on the remote had been pressed. Back to 
irw and the output shows extra key presses as I posted previously. It turns 
out that when I have mythbackend loaded I get extra key presses generated 
through lirc. Thoughout I can run evtest and it shows the remote is working 
fine. There is some sort of interaction between mythbackend and lirc causing 
the extra key presses. It would be nice to know if this is happening to 
anyone else - I have lirc 0.7.2 and mythtv svn revision 7645.
