Hey, Mark. We're talking about the CE updates. Ones which we force our receivers to install. Once installed, DirecTV needs to authorize your reciever(s) to use the features in these updates. A lot of these are considered "High Risk" meaning you should know what you're doing or at the very least, read up on CE updates, how to do it, what's involved, etc.
The normal update that DTV releases is a staggered release and seeming it's just a normal type of update, can take a course of a few months to roll out to everybody and don't necessarily think it has the Mutli-room feature - or if it does, may not be authorized for use. I could be wrong on that, though. I've been lurking for a few months here before deciding to register. CE 1/22 seemed like a good candidate for me and thought I'd register here since it seems that the people here are a good group of guys.
