Samsung smart TV, Cox cable and HBO go app "sorry this video cannot be played"

Anyone else have a Samsung smart TV and Cox cable?
I've got the app to open and everything looks fine, but when I play a movie or show it says, "Sorry, this video cannot be played at is time."

It always does this and it's pretty annoying and HBO won't even reply to me.

I've also tried to AirPlay from iPad to Apple TV, but it only streams audio. Yes, my software/firmware is all up to date.
