Amazon has released an update to its Amazon Instant Video app that adds a number of new features, most notably AirPlay support. Now users can stream content from their Amazon Instant Video app right to their Apple TV. AirPlay streaming had been one of the most-requested features for Amazon's on-demand video app (it's one of the most-requested features for any video app, actually).
In addition to AirPlay streaming, Amazon Instant Video version 2.1 features IMDb integration so users can now look up cast and director information, ratings, goofs, trivia and quotes (Amazon owns IMDb). Additionally, users can now read customer reviews, find other videos featuring cast members or the director, download videos concurrently and get improved video recommendations based on what other customers have watched. Finally, the overall speed and responsiveness of the app is improved.
Amazon Instant Video is a free download.
