I had an HR34 installed on Friday. I already had an HR22, R22 (HD), and an H23. So in theory, I should have a total of 10 tuners available. Unfortunately, I wasn't home during the installation so I couldn't keep an eye on what was going on. Here's my problem: Both the R22 and HR22 were changed by the installation tech to only have one tuner enabled. I came to to the home to find he didn't install a SWM 16 as I thought he would and instead left the original SWM 8. According to my wife, he said adding equipment that would enable additional tuners (the SWM 16) would disable the whole home DVR service. I am more than certain this is untrue, who is correct? Either way, another tech is coming out this Friday to hopefully install a SWM 16. If I do end up getting a SWM 16 installed will additional cables be run from my dish? I currently have a single line going from the dish to the SWM 8.
