There was a splitter that split a coax line and then wen to one HD-DVR and to the broadband adaptor. Tech is moving that and running a new line. There was also a phantom coax on the main 8 way splitter that ran to a bedroom where no box is used, that was removed. After a reboot the HD box saw the other DVRs, but that fixed the problem last time. Before Tech leaves I will record 4 shows, have all tuners in use and see if I can replicate the problem. I guess we'll see what happens. Thanks.
