What to do when your TV shows thinkare tagged they'reas movies

My Apple TV has an annoying habit of categorizing all my ripped DVDs and bittorrents as "movies". See picture ->

This means when I want to load up an actual movie, I need to sift through dozens of TV shows to get to it. But it turns out this is an easy problem to fix:

1. Get info on a file by selecting it and pressing control-I
2. Select the video tab
3. Change "Video Kind" to "TV Show"

This works great for a small number of files. If you have more files you need to convert, dougscripts.com has a great applescript that will work (Mac only):

If there are ways to batch this in Windows, please post here:
