TVersity is a streaming service that allows streaming of internet media such as Hulu and YouTube for Xbox360, PS3, Wii, mobile devices like iphone, and more. It also streams media from your computer over your network to your media devices (xbox, ps3, wii, etc).
Currently TVersity is doing a promo where they are allowing users to download their TVersity Pro for free unlicensed BUT no expiration. If they every change this policy they will send you a key via email. It seems like buying a license is optional if you want to be in good conscience. Just put in your email and click ‘Download’. The difference between Pro and the normal is the pro can stream internet media such as Hulu, YouTube, Sling, etc
Watch premium Internet content on your TV (including full episodes), from sites like Hulu (US only), BBC iPlayer (UK only), Joost, Sling, and many more (a full list of supported sites is available here).
