Your instructions are identical to the instructions in the manual of the RM991.
Not quite the same - manual step 4 is completely omitted.
As for the Starhub. One suspects there's not much that can be done. The response of the box (flashing green light) suggests a faint possibility of its having received unclean learns, but I would have expected intermittent operation if that were the case.
Someone with a better understanding of IR protocols may be required here, but at the end of the day it is, I'm afraid, only a Chunghop.
