Series Link is the responsibilty of the individual broadcaster @John22, ITV are usually very good compared to some of the other broadcasters such as the Discovery group.
There were significant revisions to the schedules of ITV and BBC 1 for the period Saturday (onwards) which seemed to be introduced on the Freeview EPG and the Youview EPG on Friday. this is due to the BBC and ITV only finalising which World Cup games they were covering in the round of 16 and changing their afternoon and evening schedules Whether that caused any of your issues I cannot say but I would expect given that the World Cup is now in a knock out stage with potential for schedule overruns due to extra time and penalties there are likely to be an increase in recording irregularities. Plus in the case of the BBC it is likely that the Wimbledon coverage will result in several changes some at very short notice to the BBC1 and BBC2 scheduling.
