As the title suggests, I'm upgrading to the Whole Home DVR service with Interest connectivity. I currently have 4 DVRs (3 HR20-700s and 1 HR21-700) and a slimline dish, which has 4 outputs going to a 4x8 switch in my basement. The above set up works fine, using all ports on that switch. When the tech arrived last Friday, he said he'd need to run a new line and replace the LNB. I asked why he couldn't just use one of the 4 already there and he went on to say he was worried about corrosion or other non-sense. I was said fine, do what you need to do. When he realized my basement was finished and he didn't want to pop 50 ceiling tiles to run new cable, he said my lines were probably fine, but that now I'd need a 16 SWiM switch since I have 4 DVRs. He said the SWiM 16 using all 4 of my existing inputs and that I'd need that one since I have 4 DVRs and need another spot for the DECA to my router. I asked why that was since he was only using 1 line (hence the SWiM part) and he said even though you are using just 1 line that he needs to 'cap off' the other line on the switch - basicly saying the switch would need to have 2 outlets per receiver or DECA, regardless than only 1 is running to each receiver - is that correct? They didn't have the switch and had to order - it's supposed to be in today and they are now coming out again this Saturday to install. While he was there, and before he said he needed the 16 switch, I asked about if he would be changing out my receivers. He said no, to which I replied I wouldn't mind if he did if it was for the new HR24-500s.... he said they weren't any better than what I had. We politely went back and forth for a minute before I gave up - I wasn't going to argue with him about it since it wasn't part of the ticket. However, as he was leaving, I asked again about swapping them out since he had to come back again and he said yeah, he's just gonna swap each one out to, so it looks like I might be getting 4 HR24-500s AND a 16 switch.... I'm not complaining if this goes now as planned, however, wouldn't this have worked with the SWiM 8 switch?
