I don't think (at least I didn't see it on the TV Everywhere list) NewsNation out in the list of TV EveryWhere channels for Vidgo. It is available via the Fire TV Vidgo app so I was wondering if there is a way to manually add it the Channels DVR?
Vidgo is not a participating TVE provider with news nation. So no it can’t be added to channels. The vidgo apps don’t use tve as their source
NewsNation CAN be added if you have a link to the M3U file and the epg Guide
