It all started with Netflix. As the DVDs-by-mail service began its move into internet streaming, it quickly realized people didn't want to sit in front of a PC to watch videos. So, Netflix teamed up with Roku to develop the first Roku box, a small Wi-Fi enabled set top box that streamed Netflix videos (along with other streaming content) to TVs. As bandwidth to the home mushroomed, Roku boxes began streaming video in 1080p HD about a year later.
Compared to contenders like dLink's Boxee Box and Apple TV, Roku's latest offering, the Roku 2 XS remains the strongest (in price and performance) and most successful among the set-top boxen.
Western Digital, best known for its hard drive chops, entered the fray in 2010 with two media streamers, the WD TV Live Hub and the WD TV Live Plus.
But now the company has refreshed its streaming program, and has released two new boxes with improved capabilities that seem intent on out-Rokuing Roku.
We tested both boxes: the new WD TV Live device ($100) which, like Roku, streams internet video and audio "channels," and the WD TV Live Hub ($200), which does the same thing but also comes with a built-in 1TB hard drive.
Both boxes also integrate into your home network, making all the video, photos, music and everything in your iTunes library on your PC or Mac available to stream to your television.
When testing the WD TV Live, I found setup to be a no-brainer. You'll need an HDMI cable (Why the hell isn't there one in the box?) to hook it up to the TV if you want HD. Otherwise, composite or component cables will do.
I do have one pet peeve about the on-screen setup procedure: All the authentication data is entered using the super-simple remote control. You have to scroll around to each individual character on the on-screen keyboard, press OK on each character one at a time. First you do your network settings, then your ID and password for each of your subscription services – Netflix, Hulu Plus, Spotify, Blockbuster, Pandora and so on. It takes forever, and it's maddeningly repetitive.
