Sorry ppp, I';ve just gone back and checked and you're right.
I suppose what you could do (very sneaky this) is subscribe to the movies of the sports as part of the "world" subscription, get it installed and then cancel the movies or sports on your second day, saying you don't think it was worth it after all. That way at least you've got the installation done already then!
Best to check the small print to make sure there's no minimum subscription length, but it might work!!
