What happened to my 30-second skip?!

I've long done the remote hack of changing the "jump to end" button to a "30-second skip" button. Only today I discovered that it suddenly stopped working! No amount of trying to reprogram it will re-instate it.

I'm guessing that there must have been an update sent out last night or today. Did this happen to anyone else? Any idea what we can do about it?

thanks!
