Has ITN not shortened its hours because of the recent arrival of the BBCi channels on SDN? When they're showing matches, it has a much better pciture than the ITV Sport Channel did, so they must have much more bandwidth allocated. Perhaps it'll disappear, and ITN will return to longer hours after the World Cup!
ITV Sport (and it's associated channels Sport Plus and Sport Select) was not on SDN - it was on D3&4. Only the main ITV Select films & porn service was on SDN.
I had heard that ITN did not pay for their DTT
carriage when they were only on for 3 1/2 hours a day, perhaps they still are not paying for it and SDN were only being generous by allowing them more time (if they were paying I would've expected them to have gone 24 hours as soon as ITV Select left) but that offer has now ended in the face of the beeb offering to pay for space.
Having said that, I think there was the capacity to run up to 5 ITV Select services at one time, as there was always a time (at the weekends usually) when all 5 of the ITV Select movie channels were showing a film.
IIRC, ITV Select 4 (I think) had it's hours cut in February which gave ITN more space. But there should still be space to run ITN alongside the 2 extra BBC channels since ITV Select has now gone and made a lot of space available (indeed, they have done exactly this all throughout testing).
I think it's more likely a cost issue that ITN's hours have been cut, in which case I wouldn't expect to see any extensions again for quite a while.
I'm just glad that I only have to endure DTT for another couple of weeks until I get Sky back.
