For video, I use Handbrake to rip my DVDs and some TV shows (TV shows are hard work...) and import them into iTunes after editing the metadata using MetaX. I have ~250 films loaded. I use Apple TV2s to play the films back. It has convenient separation of genres to allow us to quickly find the right movie to play. And at least in the U.S. there is plenty of streaming content to rent online.
