Hi @jay82p thanks for your post here in the Community, although I'm sorry to hear of your concerns raised.
This is a strange one, as Stream shouldn't be showing if you don't have a Stream box and you're simply trying to play regular On Demand content such as BBC, ITV etc.
If this is still happening for you, can you provide a screenshot of what's happening please?
Thank you for your reply jay82p.
Can you please confirm how your box is connected to the Hub? Is this wired or wireless?
Also, can you please confirm if you have more than one box in your home and if so, does this happen across all of them?
Thank you for confirming this @jay82p
Is your V6 box connected to an Ultra HD 4K or 8K TV?
Do you know if your TV supports HDCP 2.2? If so, please ensure that your HDMI also support HDCP 2.2
Do you have any other equipment both audio or other connected into your TV at the same time?
