Great how-to. The free version of Google Earth does not allow you to do certain things, like produce paths. So, I hacked that together by editing the .kml file in WordPad (ah, brings back memories of html before wysiwyg editors). After producing some stunning tour animations on-screen, I quickly wanted to be able to save them as a movie. The problem is, you can not save movies unless you buy the $400 Pro version of Google Earth, plus the optional Movie Maker module for God knows how much more. The heck with that! I figured once it was displayed on my screen, I should be able to save it. So I did. Link.
