Setting up a Roamio and Mini combo. Concerned about the old RG59 and splitters being good enough for MOCA. So the set up poster for the Mini says to go to your Premiere tivo and allow video sharing under settings, cable card and device menu. Well there is no such menu item on my Roamio Plus. The poster doesn't mention it but the Roamio has menu under network settings to create MOCA network so I activated that. Then I tried selecting the MOCA Option on the Mini and after a few minutes, it asked how the IP address should be set, obtain from DHCP or manually set. Taking this as a sign that MOCA is working I select dhcp and then it starts to download info but it took about 5 minutes, longer than the Roamio did the first time. Maybe this means the throughput over MOCA is poor? Should I be concerned about poor streaming from the Roamio? Now installing but also taking long. Presumably there's no network activity so maybe it's just device speed?
