That's great news! I really hope they at least fix CBC for hockey, and TSN.
Here are some examples, and not from 3 inches fro m the TV: the snowy static screen on the HBO logo before shows gets all macro blocky on Aliant. It does not on Bell.
The opening animation on American Idol gets blocky on Aliant, and did not on Bell. The opening animation on So You Think You Can Dance is a complete mess on Aliant.
During camera pans in hockey games, the background is blocky on Aliant, it was not on Bell.
Bell HD was not perfect, but Aliant's is softer.
These are compression artifacts. They aren't really an issue if you're watching a drama, but sports programming suffers.
