If you are using Windows Media Center to watch TV, why not tell it to immediately open live TV, without displaying the opening animation or menus?

Position your cursor after it, press Space and paste this line of code, including quotation marks:

Run Windows Media Center from the shortcut you just modified to admire the result.

A reduced click gain, and an improved user experience!
