Hi and welcome to the forum,
In the interest in collecting information: -
Which make and model of Now TV playback device do you have?
Is your Now TV playback device directly connected to your television or is it connected through a surround-sound amplifier or HDMI switch?
Which Now TV packages (ie: Entertainment, Movies, Sports) have you subscribed to?
How is your Now TV playback device connected to the internet. Is it via a wired or wireless (WiFi) ethernet connection?
The model number is 4200SK
So to confirm...
On the top and front of your device does it say "Now TV"? If it does, you have the Now TV 'black' box!
