Then I added them to my itunes movies.
How did you add them?
Did you copy them into the "Movies" folder or import them into your iTunes Library? You need to import them into iTunes using "file > Add to Library".
If you added them to the library but cannot find them, you might try to search for them with a smart playlist:
File > New Smart Playlist
Then add a rule "Media Kind is Movie"
or try "Kind contains MPEG-4".
Does this reveal your new movies?
