Hi, had this issue for some time. Even when remote was new... Buttons sometimes unresponsive, take a couple of clicks before it works... Very annoying. Have optus released a newer version possibly to resolve this issue, if so can I have one please.

Hmm okay, you mentioned the problem was there ever since it was new so it may have been a dud from the start.
Please see this thread on how to arrange getting a replacement.
check that the IR receiver is not in direct sunlight, also, worth changing the batteries to see if that helps
