This really is a black and white issue, though. The IR code learning 
either was successful and start, repeat and end codes are sent 
correctly and only once for one button press - or - the sequence of 
start-repeat-end is sent again and again by your universal remote what 
really is a single button press.

Since repetitions of start-repeat-end sequences could also come from 
multiple *real* button presses, trying to ignore them would break 
support for long presses of correctly functioning, original Apple 
Remotes in favor of fixing a single universal remote profile that 
seems to not send codes the way it should. That of course is something 
I won't do.
