Amazon offers more than 40,000 movie and TV show titles for rental or purchase. While Netflix's library tends to be dominated by older titles, Amazon includes many newer movies closer (if not simultaneous) to their respective DVD releases.
Titles begin streaming within 30 seconds of selection. There are four tiers of video quality, depending on your home's broadband bandwidth. Anything below the highest (four dots) makes for rough viewing on big-screen TVs.
