Set up Roamio OTA and two Minis at start of this month. Checked my ISP (Comcast) Data Usage and find I have consumed 300gb in 20 days - compared to average of 3gb per month before Roamio. We are connected to Netflix, Amazon and Youtube but not watching more than total of 3 hrs per day for all 3 TVs. Is this jump in data usage the norm for Roamio? Any settings or other ways to reduce this so I don't have problems with ISP/Comcast?
