To be honest between work and home connections its been pretty rubbish, anything over a certain time for me doesn't play at all, 4OD doesnt work, but you will sit through the 4 ads but it wont play the actual programme, 1080p playback does not stream most of the time.
Videos not playing the correct time of even displaying the correct time, have had a few 5min music vids display at only being say 2mins 34 secs long etc.
