I cannot tell you how to duplicate the problem. Next times it happens I will try to get a Tracker ID for you. But when I had the screen freeze problem I could not get an ID or even a reaction from the Roku by pressing those buttons. And of course, if those buttons are not functioning as a part of this issue, there is zero change of getting an ID.
Thanks,
Rob
