As for that slingbox idea, yeah, I thought about that.. wonder why there's not a website that would do something like this? I guess it would be a copyright issue, huh?
I can still see a couple of analog Canadian stations here in Seattle. They're quite noisy (snowy). Analog kept working when the signal got weak. OTA DTV has quite a bit of forward error correction ability engineered into the ATSC standard so it looks perfect right up to the point where the receiver can no longer decode valid data. Digital signals are prone to that phenomenon, referred to as 'cliff effect' where, when close to the minimum, a slight decrease in signal to noise will produce a dramatic increase in error rate.
