Performing tests, so should know soon. Also set up tests for end of the days programmes, where it should change from HD to SD.
I'm not trying to state it as fact, just raising the question of whether it might be the cause of the recording issue.

It is more complicated than switching from SD to HD, which would be the situation for the start of scheduled broadcasts, changes in the other direction aren't too important. SDT linkage switches to a completely different service going in and out off-air periods, so should adapt to the parameters of that service. It is more complicated though because recordings, on both Freeview and Virgin use identifiers specific to recording and that could be an weak point with potential problems. Your experiment will be interesting but this switching has been ongoing for years with no reported problems.
Not the same mechanism but, when Virgin removes channels, if a user is already "tuned in" they can sometimes continue to watch after the channel is hidden from the EPG. Info may even show that the channel then has a completely different channel number, which is not in the normal EPG range.
I wonder if the recent problems were not related to normal switching. Did the same problem happen with viewers watching live? If there is a problem, no doubt it will be repeated.
