I would like to add a 5th tuner to my installation. I currently have a traditional slimline 5 with a 8-port multi-switch supporting 4 DVR's (HR-2x). I'm running unsupported MRV over my cat 5 home infrastructure. Unfortunately, the room where I wish to install the 5th tuner has a single RG-6 run. My preference would be to retro-fit the legacy LNB with SWM, since all tuners are SWM capable. When I called just to request info on how the installer might accomplish this, I was told that the installer would use his discretion depending on available hardware, but that often they would add a second multi-switch and cascade from the first. This seems unnecessarily clunky/cumbersome. As I'd prefer something more eloquent, I considered biting the bullet and paying for the "supported MRV" which would require the installer to make the SWM exchange, in addition to the tuner. It seems silly that I'd have to go to this trouble, not to mention the additional expense, just to get the additional tuner with the installation hardware I prefer. Is there any way to avoid this?
