DVR not following instructions

Quite Tired of COMCAST trying to dictate what I watch by consistently recording old content that I have already watched before simply by saying it is new content or not even having episode data. for nearly a year had old episodes of home improvement record simply because there was no episode data. On same subject different issue . When I wait for months for a new season of a show I'm watching and a week prior to the new season the prior season being recorded against my will when clearly I did not ask it to do that .. plain and simple comcast is trying to force feed contact to be recorded by error or design. If alexa or siri or ever cortana tried to pull this they would be bashed across the room off a concrete wall.
