This is something that is driving me crazy. I can get Media Center's notification icon to pop up the status about 80 percent of the time I boot my HP machine, not at all on a Compaq Laptop, almost always on a old Compaq desktop that can't even record HD due to processor and memory problems and about 20 percent of the time on my Dell 9100 Studio machine. I can't find any setting anywhere that makes this work. No difference between warm boot, cold restart, etc etc. Obviously something needs to load to make this work and when it works it's a live reading. If you're update is running you'll get "testing internet" and various downloads with percentages and finally a finished and then next update time.
Any clues where to look to make it work?
