I'm also puzzled by this conclusion by the BBC. But I haven't viewed more than a few of the 960x540 examples, so my findings may not be typical. > More importantly BBC Four and to a lesser extent BBC 2 have a lot of > programmes about paintings, sculpture, architecture and nature where > there is a lot of fine detail and little motion.

I need to be able to contact someone further 'up the stack' to ask more 'policy' questions I guess. I know more about the radio side, so I don't know how I'll get on with the tv side. [edit] Just sent an email making some of the points. I also added a comment of my own that I'd *much* prefer "Sky at Night" as the 1280x720 25fps than a lower resolution. Time will tell if I manage to get someone 'higher up' to be willing to discuss this with me.
