I just got a Roku Ultra and have attached it to my LED (with sound bar), blu ray player and cable box (charter DVR) yesterday. In a single day the Roku has randomly tried searching for the “lost remote” 3 times. This has caused the t.v. to turn on or has interrupted us watching t.v. Or movies on our Blu ray player. The only solution I’ve found is unplugging the Roku. Am I missing something? Any advice would be helpful.
