iTunes: remove entire video folder, leaving 'purchased' only?

[alexjholland]

Hey, I have never used iTunes for videos, as it doesn't like the codecs I use.

Having recently got an Apple TV though, I've been downloading quite a few films and starting to build a collection of snowboard/skate movies on iTunes.

However, my video folder's contents have somehow been splurged in. It's a random, unsorted splatter of films that happen to have compatible codecs, that I don't want removed.

I want iTunes-purchased films in the collection on my computer ONLY.

How do I achieve this?

Thanks
