Apple recently posted three new support documents for the latest version of iTunes. The first two show users of the application how to add and watch compatible videos. The third is for Mac OS X v10.4 Tiger users and shows them how to sync their contacts and calendars with iTunes.
The documents include: “iTunes 4.8: Adding videos to your library,” “iTunes 4.8: Watching videos,” and “Mac OS X 10.4: Use iTunes 4.8 or later for iPod syncing.”
