And quicktime can be called through system events.

tell application "System Events" to {Name, full text} of every  
annotation of contents of QuickTime file ("" & (choose file))

		{"Full Name", "Artist", "Composer", "Album", "Track", "Creation  
Date", "Comment"}
		{"Happy New Year", "Spike Jones & His City Slickers", "Eddie Brandt,  
Freddy Morgan", "Dr. Demento: Holidays in Dementia", "16/17", "1948",  
"album 1995"}
