The method comprises, for each media data item: in a seeding phase; storing the media data item; receiving requests for the media data item from a plurality of users; determining the availability of the requested media data item based on the associated rights information; transmitting the requested media data item to the plurality os users: and storing information identifying the media data item, the associated rights information for the media data item and a list of users who have received the media data item. In a peer-to-peer phase the method comprises receiving requests for the media data item from at least one further user; compiling a list of sources of the media data item in a peer-to-peer network based on the list of users who have received the media data item; determining the availability of the requested media data item based on the associated rights-information; transmitting the list of sources to the at least one further user to enable the user to obtain the requested media data item via the peer-to-peer network; and storing information identifying the requested media data item, the at least one further user and the rights-information of the requested media data item.
