I'm sorry, I have been at work which is why I am late replying to your answer.
I think my query was misleading. We aren't having trouble using the X box, that is fine. The problem is with the TV reception, we are having to watch all TV programes using a scart lead, and the quality of the picture is rubbish. Our TV was HDCP compliant we had a good reception but now its not.
Thanks Rusty I'll get a new HDMI cable and see how we get on
