The rep is wrong, it's as easy as that. The way I read the OP is that the HR34/44 will give him a total of eight tuners and he shouldn't have to upgrade to a SWM-16!
Yep clearly it says HR24 and H23, That's 3 tuners
Genie is 5
Swm 8 or Swm LNB will work fine.
And yes every recording will be accessible from every receiver connected to the SWM system. (HR- H21 or Higher)
One thing though, H23 may need Deca adapter in order to assess and make recordings.
And you can't set a recording from one DVR to another.
Which has never been an issue for me.
Also H23 can't do Video on Demand, you would have to record VOD off of one of your DVRS in order to watch it on H23.
H23 can't pause and rewind live tv, But hitting record fixes that issue.
I prefer the H series rather then the Client boxes.
No interruptions by recording conflicts, and much faster performance.
I will never have a Client C31/41 until Directv forces me too , and even then , I would switch providers if Directv starts telling me what equipment I must have. LOL!.
