Further to my question above, I may have the answer. I surfed other forms and found someone who was having the same problem. While that person has a different box (not a GooBang one) they offered a possible solution. They said to check the box's CEC options in the settings menu and make sure they were turned on. The CEC is the HDMI-CEC cable that connects the box to your TV. I checked the box's settings and found them to be turned off so I turns them on. Also at the same time the GooBang people replied to me to make sure my TV's HDMI-CEC settings were disabled. I made them disabled and then tried watching a movie on my new box. Got through the whole movie without it ever turning itself off. Hope this helps others.
