Has anyone found a way round this yet? Had to watch the match on my phone on Saturday again due to having a Google phone, the only way I can cast my screen to my TV is via chromecast but Ifollow blocks it from actually showing the game on your TV screen. So annoying.
We bought a new TV fairly recently which has an in-built web browser, which I've used successfully to watch the Stoke and Millwall games on the full screen. I'd expected that it would have issues displaying the video, given that it's not one of the common browsers, but it worked perfectly. If anyone has an equivalent option on their TV's, it's worth trying out as a solution.
What I've done in the past is to first cast my empty google search page to chromecast on the tv then go to the BFC site etc on the pc, then when on enlarge the video panel to fullscreen. It's not the best way if it buffers but you can try it. You've got to have the chromecast icon on the google screen of course.
