You can watch btsport on ps3 and possibly Xbox instructions inside--->
Hi I've been doing this for other streaming sports websites and was curious to see it works well with the btsport website.
You install a piece of software on your pc called displayshare (google it) and it creates a media server that mirrors whatever is running on your pc desktop.
So run the program on pc open the btsport website , get the stream running , switch to full screen then go to ps3 and search media servers and it will show in video list, select it and there you go full screen footie on your tv with sound. Never tried it on Xbox but suspect it will work on that as well
