I just upgraded my HR20 to a HR44. Called DirecTV to ask why they didn't include return shipping with the new receiver so I could send back the 20 and was told they didn't need it back. They are sending me an envelope to send back the access card, of course. My question, what should I do with the HR20? Should I hold on to it for parts, sell it for parts because I'm fairly certain you can't activate it even with a new card correct? Or should I just throw it away?
