Unfortunately Telus doesn't control what HBO decides to air on their channel. The problem when broadcasters change what they air at the last minute is that they rarely if ever submit updates to their guide data so the schedule shows the original data. I've noticed a few other Bell owned channels (Bell controls HBO Canada) that are bad for showing wrong dates for newly airing shows in their guide data.
