I'm aware the other thread has been locked, so here's the reply I got from the duty officer at ITV. Please feel free to merge it with the other thread.
"Thank you for your email. The following response is from the Scheduling Department at STV.
We are sorry that you were disappointed with the change in the schedule. Unfortunately stv was unable to show the Marseilles v Liverpool match due to contractual issues, which meant we were forced to change the schedule at the last minute.
Please allow me to explain the circumstances which led to the unique situation that occurred last night. stv is allowed to show two games per card of fixtures in the Champions League competition. UEFA moved the Celtic match to last week, which we obviously chose to cover, taking up one of our allocation. Normally this would not have caused an issue but with ITV4 showing the Chelsea match last night, and as this is broadcast into Scotland, the Chelsea match had to count as our second match. We were not informed of this issue until the last minute. As such, if stv had shown the Liverpool match, we would have been in breach of our contract.
We understand that this last minute change was a disappointment for viewers who were looking forward to the game. We at stv were also disappointed to find ourselves in this situation. On this occasion, we were notified very late in the day of this issue which meant we weren't able to change the listings in time. As soon as we were aware of the need to change the schedule, our continuity announcers made viewers aware.
I hope this helps explain the circumstances which led to this last minute change in our schedule. Thank you again for getting in touch, we value your comments and take on board all feedback.
Regards
ITV Duty Officer - TT"
