Today, Dixons Retail plc (Currys, PC World) and Rovi launch a UK-based VOD service under the retail giant's Knowhow paid-support brand (think: Geek Squad with more overcharging). You'll be able to buy and download movies and TV to your Windows PC or stream them to a Mac using Rovi's DivX technology with adaptive streaming. The platform is promised to swell to include smart TVs, Blu-Ray players, tablets, consoles and smartphones through 2012. You'll be able to register up to five devices with the service and switch between them as you wish, as long as everything's connected to the internet. Selected movies are available to rent for around £3 ($5), or can be bought in SD/HD for £13 ($21) / £18 ($29). Just as an FYI for consumers planning on signing up: most of the titles are available to buy on DVD for around two-thirds of that price, if you can bear to wait a couple of days.
