I have absolutely no working experiance with that remote, but I did come across a picture of it that reminded me of a digital universal I was considering. If it is the same one, I was warned that it isn't entirely compatible with Vista or updates of Windows after 2006. Maybe that is why it is considerably cheaper than the Harmony? Just a theory.
Sorry if my response is way off in relation to your question; you used lingo that may as well been Japanese to a simple English speaking ol' fashioned analog TV user.
I have a feeling the more learned universal regulars will be of more help to you with this, but in the meantime you could always give this link a shot. It is a software update:[Link: esupport.sony.com]
Really hope you get this sorted out. I feel your pain... remotely.
