ah, yes, WB allowed another activation while Marvel did not. The challenge I guess with the Digital Copies is that they aren't bound to an online account, so they don't provide a centralised mechanism (like iTunes) for more versitile management.

Just to clarify, iTunes is also DRM, not a differnet format again? iTunes was offered as a target, if I had chosed that rather than Windows Media player, would I have had more versitility?
