marquee channel202

Help, I feel like a dog chasing its tail. I have talked to 3 different support people and got 3 different answers. The problem is I cannot receive the Marquee channel 202 on my TV’s with the small adapter boxes. I can receive it on the TV hooked to the main cable box. All 3 TV’s are hooked up the same. A coaxial cable from the box to a VCR and from the VCR to the TV with a coaxial cable. Person 1 said I needed 2 newer adapter boxes. Got them Serial No.’sPAPW01299068 and PAPW00988333 and no change. Did the person in the Xfinity store give me the correct boxes to receive channel 202 ?  Person 2said a needed to convert to HD and get a new main box, but I am getting202 on the box I have (Model MCSS9063 Ser. MA1945EH1196). Person 3 said my problem was that I am using coaxial cable and not HDMI connectors. I cannot use HDMI cables and as I stated earlier the main box gets 202 with coaxial cable. I am old and not technically savvy so please make your answer simple, all I want to do is watch the Cubs on my other TV’s not connected to the main box. Maybe I need a tech to come to my home and make it work. Thank you.
