I've been doing tons of searching on this.. and the best I can come up with is that, for VISTA, you can use:
Windows Key + Alt + Enter

to trigger/start MCE/Media Portal..

But I can't seem to get that to work in my XP Pro..

So is there a keyboard-shortcut method of triggering MediaPortal in XP...?

The objective is to try and use GlovePIE and a WiiMote's 'Home' button to trigger Media Portal like the Green Button on my MCE remote does...

The scripting for GlovePIE looks like this (for Vista MCE) but doesn't seem to work for my on XP Pro SP3..

   if pressed(wiimote.Home) then
      press(key.Windows)
      wait 50ms
      press(key.Alt)
      wait 50ms
      press(key.Enter)
      wait 50ms
      key.alt = true
      key.alt = false
      key.windows = false
   endif

This doesn't seem to do anything...

Thoughts?
