On the television side, can you congratulate them on the fact they now have a system in place to allow customers to test software before it goes live.
Now on other things:
Full BBCi intergration - And if done properly, would be better then the Sky version.
Channel numbers - Start to advertise the fact now, ready for a change, say in 6 months time.
PVR - As much as a VOD will be useful, a PVR would be the cherry on the cake. Even better, a PVR tied in with Tivo (I know a pipe dream, but hey

)
HDTV - Start planning now. End of Story.
Set Top Boxes - Since NTL own the boxes, can we get some quality control on them.
Finally, any chance of a CS service on Sundays?
