Thanks for the update, but it will be moot for me come this weekend as I am going to just return the device (before my January 31st deadline). I even moved my Roku Ultra LT so it was powered from different wall outlet with a different surge suppressor, and I still see the problem. This last time I was just casting YouTube from my phone to the Roku. It is EXTREMELY sad and disappointing that this new Roku Ultra LT model performs so much worse than my 6+ year old Roku Premiere 4620 model! With Roku putting out such sub-par products now, I am seriously considering migrating away from Roku to other devices.
