I hate the way Itunes saves Movie files inside my music directory! I save my movies in my USER<MOVIES folder. If I want to keep it updated I have to go into preferences and turn off the "Copy files to Itunes music Folder" then goto "Add to library", add all my videos, and then recheck the box for my music.
God forbid I forget to do this before opening a video file in Finder!

I've come to the realization that I'll just stick with Quicktime to handle all my videos as Itunes is a pain in the ***.

I would love to see an "Itunes Video file location" preference under the PREFERENCES< ADVANCED<GENERAL tab....Right next to the same preferences given to music.

Now I suppose I'll use Spotlight to find all the duplicates.. XD
