Two receivers to one TV

You want both receivers connected to one TV? And, you want to watch from both on one TV at the same time? You would need a special HDMI splitter that did PiP for both HDMI inputs. 

Thank you for your reply.  My goal is to record programs on both receivers but only watch one at a time (recorded programs). One would be "primary" for live watching and to watch recordings. 

Would a splitter work? then connect to separate 'source' on TV (similar to having a Roku installed and accessed via separate HDMI source)?  I'm concerned regarding signal and receiving / recording on 2nd  DirecTV Model DVR HD24-200 while watching 1st DVR HD24?  

I'm not technical so hope this makes sense.  Thanks.

Would this splitter work?
DIRECTV 2-Way Wide Band Satellite Splitter for SWM Systems (SPLIT2MRV)

Now I understand you. Yes, just have two HDMI ports on the TV and two HDMI connections, one to each HR24’s Hdmi port. If you have a SWM system that splitter will work fine. In the case that room has a power inserter providing power to the SWM LNB then the power inserter goes into the RED POWER PASS port on the 1x2 SWM splitter.

Thanks so much!  I'll give it a try.  Wish me luck :) 

Remember you will be paying for 2 TVs still. DirecTV was only intended for one box per TV.

Is your issue that all the recordings overlap needing more tuners, or that recording space runs out too quickly? If the latter, you could get an external eSATA hard drive (max compatible 4TB) to use instead of the internal 500GB. Then you could repurpose the other HDDVR to a different TV or deactivate it to save you some money each month.

But if the issue is tuners, then a regular Genie would be the more capable and cheaper way to go instead of 2 boxes on one TV. Certainly make the decision that is right for you. Though I am curious, what exactly is your issue with the Genie? With 5 tuners and 1TB internal space (supports external with no known hard cap as many have used 12TB or more) and only paying for 1 TV instead of the same one twice, at first look seems the best way to go.

Thank you for your note.  I believe the Genie is "wireless" .  My WiFi is not the best.  Plus, there is a  comfort level with the present service that I have had for many years.  I'd like to keep the recordings that I have on my 2nd DVR if watching and adding programs to it is possible and easy.  Ultimately, once I give away the TV, I may cancel and return the DVR after watching the present programs  if I can't easily add the 2nd DVR to my one TV with the primary DVR configuration. Thank you again for your thoughts, definitely good ideas for consideration. 

Techs like the wireless setup as it is faster so they can get to the next job but you can get wired minis.  The wireless minis setup a separate WiFi network with the WVB that doesn't use your home WiFi network.

The Genie is wired on the coax like your other boxes. It can connect to your home internet by WiFi for optional On Demand, but you can still wire that into your system as well by Ethernet or a BB Deca to send it over the coax. It is still wired from the receiving dish in the first place.

Understandable. We as humans though adaptable are not a fan of change. Only make changes that work for you, and not change for change's sake (like preording the new model phone every year as some are prone to do).

This would be a good reason not to rush an upgrade. Recordings do not transfer from the replaced box. So definitely be caught up first if you do ever choose to replace it.

As a caution, I would suggest avoiding the Genie-2 (HS17). This one box only allows Clients, meaning all boxes on your account would be replaced. That would lose all your recordings and independent reliability. A regular Genie (latest HR54) to replace a single box would be the safe way to go.
