Recording PPV

I have a few questions,

Can you record PPV programmes and then watch them back when you want (paying once, not again) or are you charged each time you play it back?

Also, if you record freeview of an adult channel (being abit cheeky here) but as recordings start a few minutes before and end a few minutes later than the programme, would you be charged because you are viewing a few minutes content that is only supposed to be seen by paying customers?

I hope you understand what I mean, if not, please ask.

As far as I know you can record PPV to the Sky+ box and watch it when you want, but you can't record it from the +box onto DVD etc. Not legally anyway.

You will not be charged for a program unless you actually order it.
