Looking for OSX Smart Folder help from a power user.

I'd like to create a smart folder that displays all folders containing particular files.

Simply I'd like the Smart Folder to display a folders that contain sub-folders containing a Video_TS folder.

This would give me all my movies from all my drives in one place.

I know this can be done by tagging the movie folders with a label and then creating a smart folder to look for that label. Problem is you have to tag every new folder with that label. Also if you move the folders it looses it's label. And if you use labels a lot this option doesn't work well.

My method should be possible with the smart folder options but I can't figure out how to get it working.

Any help?
