I think there's a bug with the YouView series link.
I want to setup a series link for a program on a HD channel, but when I check the schedule its setup the series link for the same program on a completely different channel. Its as if it checks the guide to see when the next showing of the program is and sets the series link on that.
For example, last night I set a series link for Friday's Corrie on ITV HD (its not for me honest 😉 ). I checked the schedule and its set it up for Corrie on ITV2 instead of ITV HD.
