ok, thanks for adviceG'day @jef s and welcome to linux.org
I don't watch a lot of TV but have you tried Googling
sky go linux
and you can narrow the search by putting linux in quotes
There are some references to Moonlight and Pipelight as acting for Windows Silverlight but you would be best to check this.
What Linux are you using, might help, too
Good Luck
