First of all..Long time lurker and 1st time poster here. Thanks to everyone for all the great info that I have received here over the years.
Just to comfirm how I am reading this... D* will allow the HR20 to be used without a active phone line. I am also thinking of dropping the land line and going Cell only and that was one of the things that was holding me back.
Do you need to have it 'activated' on a land line first?
Any more details would be most appreciated.
Officially from DirecTV a phone line is required for all receivers. They will tell you that and insist on one during an install.
Technically the only reason it's needed is to order PPV via remote.
Also, although very rare, people with sports subscriptions can have trouble without a phone line. Again, very rare.
Tivo based units require a phone line to call into Tivo to report home and for activating software updates. If you have no phone it will annoy you once a day to call in *but* the Tivo will continue to function just fine (but you can't get any software updates).
