CUE started on Freeview last week sometime. I hadn't seen it mentioned on here so thought I would say something.
The press release on Freeview mentions "co-operation" with Sky whatever that means. I thought that it had been switched over to Freeview from Sky and Sky were just taking the freeview transmission, but that doesn't seem to be the case as it is out of sync when switching between the 2 on my TV.
