Getting a bit of stuttering on watch some replays last night when it was upgraded, and they have removed the guide form the watch screen, so can't flick between channels)
They made the choice if you start watching something, they will start playing from the start of the program, then press the button to get to live, which again is not great for channel surfing, but saves you seeing the score near he end of the game you are about to watch. (conflicted here, a choice would be good ala Spark Sport)
I also note there were 13 'live' events - if by live they mean playing out replays & highlights :)
Some parts good, some parts bad.
See how it handles the rugby this weekend
edit: login from mobile for the tv app is so much better (although curiously, they didn't spring for either a new short domain to type in - or showing a QR code on the screen, first world problems I know) I can now go back to using a decent password, as their android tv app didn't allow the use of my phone keyboard.
(same as spark too, think they possibly had the same UX devs)
