So I'm getting an HR34. I currently have an HR23 and HR24. Where the HR34 is already has a single coax run to the splitter. (I have a SWM dish with a single cable to a splitter that splits to signal to two cable runs, one for each DVR). What will the install look like with 9 tuners? I just want to make sure the installer does it right so I'm able to do 9 tuners with whole home and internet. Will they leave the same dish? Is there some sophisticated switch? Will a single coax support all 5 tuners on the HR34? 9 tuners blows my mind.
