I have yet to buy something on live, now just a simple question!

If i was to buy, lets say the Halo 3 Picture pack... and i somehow needed to format and i lost those items....does live remember what my account has downloaded and let me download it again?

if so...then awesome, if not...then i dont think im gonna bother

Yeah it should save the fact that you bought the item, becuase before they were planning on upgrading the hardrives I remember that service coming out where you can download tv shows and movies from the marketplace (we don't have that here in Canada) but the problem was the 20gb hd was not big enough so they said you could always delete the item and download it again without any further costs.
