Just for information's sake, I have noticed fairly consistent staying power of the clear QAM channels here. I started tracking in December, and although I have been told it's gone (by the repair guy), I still have most of my original channels.
For HD, I only get TVO, CTV & CTV2 as the "local" channels - TVO changed once. I recently lost the NFL network altogether, but still have Food, E! and one other.
SD is not recorded often, but treehouse moved once, but all local stations are in the same location. Definitely lost some higher level ones, but probably only 2.
Pay networks on freeview are definitely fickle - I never trust those staying.
