It's a bug introduced in Firmware 1.0.16 for the Humax HDR-1000s G2 freesat box. It only applies to this box, not any Freeview boxes.
I thinks you've misinterpreted what I've said Graham.
Edward gave a scenario which is pretty much as how I use my current Freeview PVR now.
So when I do decide to buy the HDR-1000s it seems that until if and when Humax fix this issue then its a little worrying that I won't be able to use it in the same way without the risk of it not recording anything.
