CTV HD is certianly doing something screwy. My set picks up 40-4 and re-labels that subchannel 9-1. My set also picks up 40-1 and 40-2 but there is no picture on those sub channels. When I select 9-1 on my tuner I automaticaly go to 40-4 for picture and sound. When I perform a scan to automaticaly pick up any channel available again the set picks up 40-4 (re-labels that 9-1), 40-1 & 40-2. So I guess the subchannels 40-1 and 40-2 are active with black being fed into them.

CTV needs to clean up their act. they also don't provide PSIP information either.
