Roku owners already have access to Netflix , Amazon Video On Demand and MLB.tv , but now the set-top box is about to get a lot more interesting. Starting tonight and running throughout the next fortnight, existing owners of the Roku SD, Roku HD and Roku HD-XR will receive an automatic (and free) update that delivers ten new content channels. Pandora, Facebook Photos, Revision3, Mediafly, TWiT, blip.tv, Flickr, FrameChannel, Motionbox and MobileTribe will be joining the fray, and while we wish the likes of Hulu and other television portals were included, we’re holding out hope that such channels will be unveiled in due time.
