Has anyone had problems activating a box they bought from EBay? I just got a HR10-250 and when I tried to activate it DirecTv told me the box was still active on another account. The person I got it from said it was never used. Is this one of DirecTv's way of getting rid of owned boxes and get people to lease? Any input on how to turn this from a paper weight to a TiVo would be great!!!
