open all files in QuickTime and mute

I want to be able to drag files onto a droplet and open in QuickTime and mute each file as it opens. Right now everything works except the only file that gets muted is the foremost window.

on open the_Droppings
	tell application "QuickTime Player 7" to activate
	tell application "QuickTime Player 7" to open the_Droppings
	tell application "System Events" to tell process "QuickTime Player 7"
		repeat with w in (get every window)
			tell window "QuickTime Player 7"
				keystroke (ASCII character 31) using {command down, option down}
			end tell
		end repeat
		
	end tell
end open

Hi,

I think GUI scripting is not necessary,
open the files one by one and set the sound volume to 0


on open the_Droppings
	activate application "QuickTime Player 7"
	repeat with oneDrop in the_Droppings
		tell application "QuickTime Player 7"
			open oneDrop
			set sound volume of document 1 to 0
		end tell
	end repeat
end open


Works perfect, thanks for the help.
