Tivo Roamio guide help

I have three Visio TVs with a OTA. I have one that is in the living room hooked up to the tivo roamio. I have 43 channels that come in good but maybe only half them have info on the guide. I have tried forcing the connection but that hasn't worked. I have this same set up for about five months and still the same. My only problem is on my other TVs that is just hooked up to the antenna will show all the info on the show and channels that won't on the tivo. So that tells me that they are available. I am just wondering if there is something that I am not doing. I would appreciate any help. Thanks
