Changing the ownership of downloadable content

[wuptdo]

Is there any way to change the ownership of the DLCs on my ps3 so they all belong to one account so i can delete the others? been tryin to dig through files/registry but cant spot anything myself.

All help is appreciated !

EDIT: Hmmmm right, i think i may have found the ownership file, if you navigate too; /dev_hdd0/home/(User No. which currently owns dlc)/exdata
You will find a selection of RIF files, each with a name relating to some DLC on your ps3, e.g. MW2 DLC2 name = 'EP0002-BLES00683_00-MODERNWARFARE2D2.rif'. I'm going to have a guess that these are the ownership files. Now what i want to know, if i moved that DLC ownership file from one User folder to another, will it change the owner? This all on one huge wym!

EDIT: Well actually i cant see any harm in doing so, so im gonna give it a go! If it doesn't work i have a backup to restore it. And its not as if its important system files either. I shall report back my findings to you guys! How ever i think act.dat file is the activation file and that may need some tweaking aswell, but its not exactly understandable in its current state :P But I'll try anyway.

EDIT: Riiight I tried to change the ownership of PS1 (medievil), from one user to another, by altering the folders.

When i loaded up my ps3, i went into the ps1 game and looked under 'owner' it reported back as '-' so i didn't quite manage to change them, just remove them.

I'm going to have a guess that i somehow need to alter the (activation file) act.dat file which is with the rifs in order to fully change the owner. However currently i'm complete novice and wouldn't even dream of knowing where to start in order to read that info.
