Not an a issue on playback for me with now stick & Panasonic tv. Here are my images.
normal playback - perfect. Used constant colour to make sure.
paused - the blocking at the bottom but no big issue for me
the blocky screen when I rewind/fast forward, but it only appears for a short time
Same issue here been going on 6 months, doubt they are going to fix it, it's very annoying and think I will be cancelling
Just been reading the thread and have exactly the same issue. It seems to be prevalent on Sky One for me.
I’m using Now TV through a Samsung OLED TV
