Earlier I was recording Pointless on BBC1 finishing at 1800 and also had a scheduled recording of Eggheads on BBC2 starting at 1800 both with a short buffer, so that there was a short overlap - but only of two recordings.
I then tried to schedule a manually created recording from 1759 on BBC1 for 60 minutes to cover the Main News and London News. The box (5000T) refused to do it. However it allowed a 60m schedule starting at 1800 exactly.
As the box has 3 tuners, can anyone explain this behaviour?
