Do you want to test your extensibility application for widescreen compatibility without a widescreen monitor?
If yes, then...
Click Start => Run.
Type 'C:\windows\eHome\ehshell.exe /widescreen'.
Click the OK button.
Using the mouse, click the 'Restore Down' button to run Media Center in a window rather than full screen.
Voila, a 16:9 implementation of Media Center.
And to get it back to normal view:
With Media Center in a windowed mode use the mouse to click the Maximize button (which is in the same position as the Restore Down button when Media Center is full screen).
