As long as you transfer points purchased from DVD, he could use them for the collections. If he transfers to you resale points you cannot use them for the collections. The MS computer system keeps track of whether points are purchased from DVD or resale. Also note that if you transfer to him in a use year he will not be able to transfer to you in the same use year. A member is limited to one transfer, either in or out but not both, during a use year, so your transfer to him would use up the one transfer right for both of you.
