Oh really? I noticed all the Foxtel and online EPGs were revised to 9:18pm over the weekend - at least they did for me. (For episode 1.)Online guide had it for the same time last night, and it went until circa 9.20. So I would pad out recording times rather than trusting on EPG times.
It's a bit annoying, because 7 must know how long it will run, given it's all prerecorded and with no live element to cause an overrun.
