It's because in instant on, when you turn it off, it immediately looks for available updates. I don't know how power saver does it. Hell, instant on wont work for me unless I turn the power saver on, turn the system off, then turn instant on back on and power off. It's really dumb. There should be just an update button that allows you to search for an available updates.

It fucks up matchmaking in games, too. I couldn't connect to anything last night on Garden Warfare, and I know it's because I was one of the early ones to get the update and no one else had it.

Oh well, hard to be mad with Dolby Digital support finally. I forgot how good it sounded.
