I have about 10 movies and 4 or 5 tv shows recorded. one movie and and one tv show are in progress. I tried to queue up another movie and there was some computer code in purple in the top left corner of the screen, but the movie would not play, the back button wouldn't work. i had to escape to live tv. Even todays pbs newshour recorded at 3pm gets the same problem, it just displays a grey screen with a bunch of geometric shapes on it. The two in progress movies/shows play fine, but nothing else will. we had a short power outage this morning which may have contributed. but the purple computer code displayed the first time i got the problem seems to be the giveaway. How do i do a factory reset, becaseu nothing will play, live tv plays perfectly.
