You may not have much luck with these codes as they don't have a large one-shot and small repeat but instead no one-shot and large repeat. Try changing the first 4 sets of numbers to:

0000 0071 0032 0000

Which effectively makes the repeating part the one-shot with no repeats. Note: You will want to use your original IR codes for regular non-scripted buttons as these codes won't repeat if used there. (See Barry's Pronto Hex IR Format doc in Classic Pronto Files section for better understanding of what I did).

Not sure this will make much difference but it might.
