Sounds good, Nick, but can it be *absolutely* guaranteed that DVB-T and DVB-S 
programming is kept exactly in step (for example)?

Although I know in practice that both feeds are supposed to be the same I 
wouldn't be at all surprised to find subtle differences between the two at 
times. I would assume in those cases the EIT now&next[1] would be more accurate 
for each feed - but, equally, would not work for the other feed.

[1] Of course, I have seen recent instances where the now&next bore no relation 
at all to what was showing...
