Rule on Subfolders not working Automatically

I have a rule that looks at my downloads folder and is supposed to open any movie file it finds in there with it's default program (in this case iFlicks). The problem i have is that the rule only works when I hit the gear icon and choose "Run Rules Now" it will not work automatically when a new video is put into any sub folder of Downloads.
When I check the "preview" icon it says that all the subfolders match the rules and like I stated above the "run rules now" command works and they all open up in iFlick as expected I just can get the rule to run automatically.
