Ya that's incorrect, I have a large family, we had originally 6 HD DVR's with whole home dvr, replaced 1 dvr with a HR44 genie, so now have 1 genie and 5 HD DVR's with 1 massive playlist.I had always been told that with the genie, 5 tuners was max. You cannot add more than that, and it requires "genie minis"
With directv the fee is $6 per receivers, doesn't matter if genie, dvr, hd receivers, SD receiver or client. So I pay $30 in receiver fees for 6 rooms( first receiver free)
