Well I've ALWAYS thought this was a crock anyway - while you technically CAN get 2 different programs out of the receiver at once, each room ONLY gets 1 tuner. So, if both rooms are watching something live, each one then CANNOT record another show at once.
Also, if the customer happens to NOT have a landline, (which more & more do NOT) then they are penalized $5 - which is the SAME cost as having another receiver anyway. (& before you mention the ethernet connection, many of those same people do NOT have these connections, or care to have them, so that's not a real solution, either) So, these same customers would be better off just getting the 2nd receiver & then each room having TWO tuners to boot.
After I explain all these things to potential new D* customers, they usually agree with me that it's a crock too, & just go with a 2nd DVR. They REALLY appreciate after they realize how quickly you can just fill up ONE DVR, let alone two!
