"Wild at Heart" series, 6th season, 5th episode has started looping in aprox 10 second segments, over and over. Refresh and FF not fix. FF will jump it way too far ahead and we lose too much of show but then it will almost immediately start looping all over again, anyway. I have rebooted, TOTAL CUT OFF OF POWER to modem and router and Roku $39.99 Walmart Roku device without any improvement. HELP!
