Hi. I'm about to purchase Roamio OTA DVR and a Mini, but I'm not clear on a few things. 1)Will the Mini (on 2nd tv) give the OTA channels coming off the Roamio OTA DVR? 2)The Roamio OTA DVR and Mini will hook to a Ethernet network, which there are inputs. Is it that easy or is there a missing part that has to be added? Thank you very much.
