Did you notice an audio lag? Sideline report from McManus was really off. Trying to contact TSN on ANY issue is an exercise in futility - they're so insulated that one eventually gives up trying to complain.
As discussed in this thread, CFL games produced in HD on TSN are not blacked out. It's been fairly consistent the last couple years.
As good as HD football looks, I'm thinking you enjoyed the final score even more. Not too often a team wins with their 3rd stringer starting the game (ask the Argos). I don't even want to think what would happen if the Esks found themselves in that situation... I'll just look forward to Labour Day instead.
