Just got Whole Home installed for five DVR's and one receiver. The installer used one 8-port splitter off the SWM-16. I noticed tonight that one of the DVRs is not getting a second satellite signal. Tried re-running sat setup to no avail. Called DTV and the support rep kept insisting that tuner 2 was bad. I tried to explain that I thought there should be two 4-port splitters instead of one 8-port. He did not agree. We ran the system test and got the error message stating the second tuner could not be used because of too many receivers. Am I correct is believing there should be two 4-port splitters?
