Store movies/tv shows from iTunes on external drive

What I would do is:

• Have only 1 library
• Make sure that iTunes is configured to keep all your media organized (and point your single iTunes Library to your preferred disk)
• When adding files to your iTunes library hold down Option/Alt to let iTunes know that it shouldn't copy the file to where your library is

This way all your data will be organized by iTunes except for the large files that should belong on your largest external disk in the first place.

Cheers...

My iTunes music folder and all of my movies (in separate folders) are on an external drive. In fact, it's a NAS RAID box, but it's mounted on my Mac mini.

You just have to load the movies into iTunes. When you do, they'll be visible to the Apple TV. Of course, they have to be in the MP4/M4V favored by Apple. If you want to watch AVIs, etc., you'd have to "hack" your Apple TV. Haven't done this, but it sounds pretty easy these days.

Maybe we'll get an ATV Apps Store soon, and it will be easy to load other apps and stream all sorts of stuff to the ATV...
