Remote Desktop 2 file copy

Hi All I need to copy a imovie file in ARD 2 to a group of logged in users who all have Network Home Folders - specifically I need to copy it to their 'Movies' folder. There's not option to copy to each users Movies folder specifically and I've tried ~/Movies but that doesn't work presumably because it isn't a full path. And I can't use the 'same relative location' option either. Any ideas ?
