a few years ago, i used to cast skygo from my pc to my chromecast by using the cast desktop beta option, at the time before discovering zgemmas and the like it was pretty decent for a bit of free tv in the living room as my dad gave me his user name and password and allowed me to use his guest login, I might add you need a beefy cpu on the pc though when doing it as it cpu intensive and if underpowered will still work but you will be watching it with a choppy frame rate, before that I used to watch skygo on my xbox 360 but then sky got greedy and made it so you cant watch it unless you subscibe to sky go plus which wasn't going to happen.
