You should be able to install the DirectTV channel/app onto your Roku device from the Roku Channel Store and access the same content.

The Newsmax+ channel/app was created to allow users to get access to the same Newsmax channel that cable/satellite customers have access to. Since you already have cable/satellite access to Newsmax, you do not need Newsmax+ channel/app if you put the DirectTV channel/app onto your Roku device.
