***EDIT AFTER CONFIRMATION*** The big difference will not be noticed by those with working receivers. If one, however, is RA'd, the difference will be solidly established in the activation of the new receiver. Basically, it is a "Setup Wizard" that was scheduled to roll out on the receivers. Being the limited number of 222Ks in the field, it was the perfect platform to release this software update into the wild. With a broadband connection and the like, a customer can roll through the Wizard much quicker to activate the replacement.
Remote programming and video resolution setup seems to be one of the big things, with activation, check switch, and other things like that being handled more efficient without a phone call due to "swap" problems. The software I believe is scheduled to be put on boxes as they roll through service (so long as they get a certain version of factory software installed). Limited release right now it looks like, confirmed with a "software" changes list. It's basically a 7 step process to receiver activation rather then having the printed instructions on paper. The only time it will prompt a call is if the receiver does not sense an active broadband (phone?) connection.
I believe there is a way to access the setup wizard via the menu. Gonna head back and test it out here in a bit. Gonna kill the box to factory.
Also, if the software release dramatically reduces the number of calls based on add/swap receivers, then it should spread further to more platforms. Its a test release.
