Can you record more than one channel at a time on sky plus?

you can record (with a standard sky plus box with standard installation) 2 programs at once, as long as you either have one of the channels that are being recorded on (you could still watch terrestrial of freeview though), or are watching something you previously recorded.

e.g. you could record sky sports 1, and sky sports 2 at the same time, leave one of the channels on so you can record both at once and switch to terrestrial or freeview bbc1.
