I won't mention his forum alias in case he doesn't want me to but I've now got the BBC HD channel.
Apparently my box simply hadn't picked up all the settings correctly. It's now working as expected and coming through to my amp in Dolby Digital. It seems I need to educate someone in the installations team that you really can get BBC HD via an SD TV !
So the only thing I mentioned in this thread that isn't 100% is my Interactive.
A lot works but a lot doesn't. In many cases it shows "application unavailable" and then when you exit it says "Do you want to exit 2 way TV ?"
I get this problem on :
Games zone / New releases
TV Extras / Cartoon Network (Hangs on loading screen)
TV Extras / Challenge
Play to win cash - They all do nothing and when you press Home it asks "do you want to exist 2 way tv"
Email & Chat / Chatbox - application unavailable
Email & Chat / Telemessenger - "technical problems so currently removed"
Email & Chat / Email - unavailable code IS002
Mobile zone
Crystal Coloumns works but I said "no way" to the 60p charge and it still took me in!
All other interactive works fine. Now admittedly I'm not going to use many of the above but it seems to point to something being wrong if none of the above work.
