It is at their end indeed but I think that HDGeorge is right when saying it is at both ends, the TV Station PSIP data and our tuners software as well. Otherwise how do you explain that most users apparently had no problem at all.

Like Daniel also pointed out some tuners might be more inmune to changes in the PSIP data since some of them do not seem to update or try to re-read the data dynamically everytime but rather just one time when the tv channel was scanned in the first time. That "behaviour" does not mean one tuner is better than the other it is just the nature of the beast I guess. In any case letting the tuner manufacturer know will allow them to release a firmware update that might adress this issues in the future.

I am glad you both now can enjoy your favorite US shows on Canadian CTV HD, ... just kidding.
