No way for Channels DVR TVE to authenticate (with DIRECTV STREAM) and stream it yet.
If and when the NFL Network adds DIRECTV STREAM as a TVE provider at their website, just follow the directions below to add it. Could be that DIRECTV STREAM hasn't negotiated TVE access for the NFL Network, or they did and it will just take awhile for it to appear on the NFL Network website. You could contact Directv Stream and ask them.
Appears they just added Xfinity as a provider at the NFL Network website, so I should be able to add it to Channels DVR now.
Works for other providers that can be authenticated at their website.
