So we are finally throwing in the towel on our three DirecTivo R10s and upgrading to HD. A few questions on upgrading our old equipment/dish/install to HD: 1. Is a phone line still required to activate new HR24 (or any HD) receiver(s)? I've tried reading old threads about this and I cannot tell if this is still an issue. We have phone jacks at each receiver, but we have not had land line phone service for a long time now. I'm not really interested in temporarily paying for phone service again just to activate receivers. Our new install will include Whole Home MRV (with Internet Connection Kit), so can the installer activate all the receivers via our internet connection or by calling in and giving them receiver ID numbers? 2. Is there any install scenario where we could keep one/some of our R10 DirecTivos working in the same environment as new HD DVRs? I assume R10s would not work with a new dish single wire configuration? Is there a way to make these old receivers work alongside a HR24 DVR? 3. I've read that you cannot guarantee receiving HR24 receivers -- is this still the case? Several threads mention rejecting the receivers if the installer shows up without them and get the install rescheduled until they can provide those HR24s. Does that work? 4. I'll be calling DirecTV and playing roulette to see what kind of offer I will get. Considering I want three R10s upgraded to three HR24s, MRV Whole Home with Internet Connection Kit, new dish/lnb/wiring install, and HD lineup, what kind of minimum offer should I expect so I know what to reject and try again or to accept? Appreciate any help info.
