I just got a free upgrade to the Genie system. A Genie plus 2 clients. I have 3 DVR's, an hr21, hr23 and hr24 on a SMI 8 and a hr23 in the back tied into the system with ethernet cable for the whole home DVR. I have been thinking it over and cant make up my mind if I am better off with just the Genie and the DVR's getting rid of the 21 keeping the other 2 and not having the client's off the Genie. Can the DVR's work with the Genie as the client's do? If I keep the 2 hr2-- then the installers have to replace the SMI 8 with a 16 but that would be it.
