Script to Hint a movie in Quicktime

I am using the droplet code that can be used to convert a QT movie to a hinted movie but i need it to run as a compiled script.I have edited the code so that it reads in an alias to a movie and exports this as a hinted movie.
This is giving me an error saying that the movie cant be exported as hinted
here is the code,any help is greatly appreciated.I thnik the problem is with the line

set myMovie to make new movie with data (alias “mscmt2003:cc10:QTSampleCode:HintingFromJava:SmilMovieFlatten.mov”)


tell application "QuickTime Player"
		--launch -- bypasses promo movie
		activate
		--my toggle_suppress(true)
		--stop every movie
		--close every movie saving no
		set myMovie to make new movie with data (alias "mscmt2003:cc10:QTSampleCode:HintingFromJava:SmilMovieFlatten.mov")
		--set myMovie to make new movie with data (the_file)
		--open myMovie
		--play myMovie
		--close this_file
		
		try
		
			set the movie_name to the name of myMovie
				-- check to see if the opened movie can be exported
			if (can export myMovie as hinted movie) is true then
				tell application "Finder"
					set the file_name to the name of this_file
					set the new_file to ((the target_folder as text) & the file_name) as string
					display dialog new_file
					if (exists file new_file) then ¬
						delete file new_file
				end tell
				-- export the movie as hinted movie
				if use_default is true then
					export myMovie to file new_file as hinted movie using default settings
				else
					export myMovie to file new_file as hinted movie using most recent settings
				end if
			else
				error "The movie “" & the movie_name & "” cannot be exported as a hinted movie."
			end if
		on error error_msg
			try
				beep
				display dialog error_msg buttons {"Cancel", "Continue"} default button 2 with icon 1
			on error
				my toggle_suppress(false)
				error number -128
			end try
		end try
		--close this_file saving no
		my toggle_suppress(false)
	end tell
