I can't really find a reason why i can't use my existing Roamio Plus for OTA antenna reception but wanted to ask. I'd rather just keep using it since I just paid the yearly subscription on it. I'm tired of comcast and now that we have amazing fiber internet, I really don't need them anymore. Being an ATT customer i'm eyeing Direct TVnow as well. Can I use it? If so, anything special you need to do besides removing the cable card? Thanks and sorry for dumb question.
