dclegg: So how are people finding HBO Now performance so far?
Not particularly good as per my previous posts but I have had better results recently...
I could not get HD quality on our 45/10 VDSL initially but after a few days of use I have found that if the stream begins in SD on the Apple TV (which is common), I could often get it into HD by backing out and restarting the same stream again. Once in HD it would stay there for most of the episode (I have been watching GOT S4 mostly with better HD results by doing this).
Just pausing the SD stream would not make it jump into HD when resuming. In my case I have to go back to the HBO menu and restart it to get it into HD.
But, yes, peak times do suffer from intermittent changes from HD to SD and buffering with the odd error message appearing during playback.
