Maybe my broadband's playing up tonight*, but Now TV is less than impressive as this clip of tonight's Game of Thrones on Sky Atlantic (via Now TV) demonstrates. I actually video-ed a couple of minutes, most of which featured the spinning wheel, but I think you get the idea from this clip.
As a live channel this is more dire than a Direwolf if you ask me...
[spoiler warning: if you haven't watch episode 2 of the fourth season yet, play with the audio off]
* According to Speedtest.net, I was getting around 30mb downloading on my laptop at the time over the wireless, which is well down on what I normally see.
