I don’t know the technical aspect of it and obviously they don’t either. All I know is I never had a problem doing it with past DVRs. And why can it be done on the android phone app but not these streaming apps. Doesn’t make sense. It’s not a high priority on their list. And obviously they don’t care about people who bought the unit but don’t want to subscribe. I don’t watch much broadcast TV aside from a few news programs so I have no desire to subscribe.
