We're excited to announce that we've fully migrated the Xbox Forums to their new home, here on the Microsoft Community forums!
As of today, going to forums.xbox.com will redirect you here to the Xbox area of the Community forums. We've moved all of your existing threads over so you can continue and start conversations with the new forums experience.
We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!
I searched Xbox One and Freeview box and saw your post from Sept last year. I assume (man I hate that word) that if it has an HDMI out you can use the pass-through feature. However for One Guide functionality, I doubt it. Money makes the world go round
and free things tend to fall to the side of the road. Best I have is to plug it and go through the setup to see if Freeview Box is one of the provider choices. Best of luck mate.
