Naturally our first stop was to try it out in a browser, and there these instantly viewable titles interface nicely with Amazon's already existing selection of instant titles. However, now above the "3 day rental" and "Buy movie" buttons (which are still there, if you want to pay for downloadable versions) is a "Watch now unlimited streaming" button, with a quite appealing price of $0.00 driving home the idea that, indeed, there's no charge here. Just in case you had any last doubts.
We then moved on to other devices, first a Logitech Revue Google TV box. We were pleasantly surprised to find that Amazon has not (at least not yet) blocked streaming on this box, and everything played perfectly. Next up was an Android device running Flash and, sure enough, it worked on there too -- well, the video plays. How well it plays will largely depend on your phone's processor and your current connection. Content ranged from slideshow to acceptable on the first-gen Droid we spun it up on. We also have confirmation that this service works on the Amazon Instant Channel on Roku and we're guessing just about anything else that'll do Amazon Instant is good to go.
To check quality we loaded up a few films that are streaming both on Netflix and here (not difficult to find) and compared them back-to-back. Ultimately the Amazon quality is good, but not great. In Man on Wire the applied film grain effect shown for flashbacks played havoc on the presumably lower bitrate from Amazon. It looked noticeably better on Netflix. Additionally, there was some detail lacking in the skin on the faces of the speakers in the film.
We also got Red Cliff going to see how Cao Cao would fare in conquering this new service. This film showed a bit more dithering in the scenery shots and the subtitles looked less crisp. So, there's definitely a difference if you're looking for it, but the Amazon content certainly doesn't look bad. And, we really like that Amazon gives the option in many foreign films to choose between dubbed and subtitled. It's also worth noting that you can watch up to two videos simultaneously on two different devices, so if you like the subtitles but your spouse prefers those awful dubs, you can each watch your preferred version together -- if you have enough devices.
