Whew, The installer just left after 6 hours on a HR-44 upgrade. All I wanted was for him to swap a D-12 for the Genie and put in a SWiM-16 since I would have 10 tuners. 5 on the Genie, 2 on a HR-24 and 3 H25's. Things went bad quick when he hooked the power line in to the wrong port in the switch and after that only one leg of the switch would work. He found a new SWiM-16 and put that in but nothing would work at all with the new switch. He then put the old switch back on and got one leg working to power 8 tuners with two of the H-25's left unhooked. The two DVR's see each others play list but none of the H-25's will see either of the DVR's. The say no networked DVR's found but they saw the Hr-24's playlist before he came. He will be back in the morning with another tech to see if they can figure it out. He took out the CCK and plugged the Ethernet cable directly into the HR-24. He said he had never seen anything like this before and he suspects bad cabling but all the receivers worked fine before and work fine now when they are hooked into one side of the switch. I am at a loss, can any of the experts here figure this out. Each receiver has been reset a dozen times.
