For a time, Roku was the only game in town when it came to streaming Netflix movies without a PC. That’s probably because development of the device started at Neflix, where Roku founder Anthony Wood toiled for a time as VP of Internet TV.The Roku HD XR takes a very different tack to media streaming, in that it accesses Internet content only, unlike the other boxes we tested. It will stream audio and video content from a vast array of free and subscription online services, but it won’t play any of your own content on your TV.If you’re a Netflix subscriber, you can stream movies on demand from that service. More importantly, you can browse and search through the company’s streaming library. With earlier models, you had to browse with your PC, adding titles to a queue before you could stream to a box such as this.
