This is right off my Directv order-They call everything a "Genie". They call their HR54 a "Genie HD DVR". The C41W wireless clients are called "Wireless Genie Minis". The C61K is called a "DIRECT 4K Genie Mini".a genie is a dvr, hr54/hr44/hr34. they each have 5 tuners and do all the work. they will work without any other unit
a mini genie is a slave/client unit that will not work without a genie
it has no tuner, just uses the feeds/dvr/ect from the main genie.
no main genie, and its just a paperweight.
