Here’s something that not everyone knows about. If you’re watching live TV in Media Center and you press “411” then “info” on the remote, it brings up an overlay that shows handy tuner info. You can get additional pages of info by using the left and right arrow keys.
I find this useful when I want to check what resolution a TV broadcast is being received at. To get rid of the overlay, just press the back key. It works on Windows 7 Media Center, and that’s all I use now so I can’t say for sure about previous versions. I think it was introduced with the Vista Media Center cumulative update known as the “TV Pack”.
