Two of the BBC's interactive services, 301 and 302, can be viewed in normal picture form in Freeview form, but you can't use the interactive feature to call up the menu to switch to another BBC channel - it has to be done manually.
I get a similar message from Hauppauge. I can't be the only one running Windows Media Center and wanting the full service from Freeview. My remote has all the coloured buttons. Perhaps they are there just to tease me. I'm surprised no one has come up with a fix to get more out of a system like mine after all even the cheap set top boxes can do the interactivity.
Thanks for the information anyway and for the prompt reply. I'm now off to explore teletext on the analogue part of the system
