Ok I've confused myself AGAIN

Is this possible and IF so HOW?

Friend wants to take lead from Sky box with chanel changer plugged into it (gizmo thing supplied by sky) that uses sky remote. Plug lead into PC so he can a)record sky programs(doesn't want Sky+ box) and b)watch Sky on monitor as it is bigger than his portable.

Have tried using digital satellite TV card but that won't show encrypted chanels.

PC is XP (media)

Thanks in advanc for all and any advice.
