Users can shop for Unbox titles directly on the Amazon site--look for the Unbox link high on the left side--but you'll need the Unbox downloader software to receive titles. Sorry Mac owners, but Amazon Unbox doesn't love you; the iTunes Store is still the only video-download site that works with Macs and iPods.
Unbox titles are divided into rentals and purchases. (There's no subscription plan, as with Vongo, and there's no streaming content except for previews.) Purchases are generally $1.99 for a TV show and run between $9.99 and $14.99 for a movie, while movie rentals are $3.99. We're not sure how many titles the store has because Amazon won't comment, but it looks comparable to the other stores. It carries most of the major film studios, with Disney as the glaring exception. It also offers an impressive selection of TV studios--seeing that it carries BBC content made our geek heart beat faster, but seeing that we could download Dr. Who episodes from several seasons, including the first, nearly made us faint.
Amazon does an excellent job of spelling out the usage rights before you buy a video--we wish the other stores would follow suit. On each page, you'll find information telling you either that rentals can be kept for 30 days but must be watched in a 24-hour period, or that purchases can be watched on as many as two PCs. That seems stingy, but it's standard for most video sites.
Purchasing on Unbox is strictly one-click, so be sure of your selection before you hit that button. Downloads are definitely on the slow side, but on the other hand, Unbox gives you a higher-quality video than most--2.5Mbps--so it's going to take some time. Downloading an 85-minute movie, for example, took us 80 minutes. Luckily, Unbox's progressive downloading lets you start watching while the movie is still downloading. We were able to start watching that 85 minute movie in only 10 minutes. You watch and transfer movies directly through the well-designed Unbox software.
