I purchases a Hughes DIRECTV DVR with TiVo; have been using it for several years. I have cancelled my DIRECTV service. They sent me a postage paid envelope for me to put this unit's access card in it and return it to them. The unit is clearly mine; bought and paid for. What about the access card? Must I return it to DIRECTV? What if someday I decide to go back to satellite? What if I want to sell the unit? Would DIRECTV furnish me or a new user of the unit with a new access card? If anyone has experience in this area, please let me know.
