I must confess to finding this a very annoying aspect of NOWTV. Amazon Prime has excellent settings for dealing with this situation.
Thank you for the suggested solution I will now get cracking with trying to sort out my unwanted programs.
I agree and I think NowTV has by far the worst interface of all the media streaming providers (for a higher standard price!). It's not user friendly and it can hang when swapping devices. Also, it can be sluggish when the player software is loaded on PCs.
