I see people selling some used HR20-700's on ebay. One such seller has a good rating and said that he bought the box at Circuit City a few months back and has since cancelled DirecTV service. I got the RID # from him and called DirecTV and they said that the box would be OK to be activated on my account. So I guess my confusion is this: Aren't these boxes all "leased" units? And if so, why doesn't DirecTV want them shipped back to them upon cancellation of service? I'm having a hard time fitting these puzzle pieces together. Someone help me understand how this situation is possible. I just want to make sure that I wouldn't be getting hosed if I buy a used DVR.
