I second that. Roku has given me a great experience. My original one went about six years and then I bought a new one about a year ago because the video started cutting in and out. The newer ones seem to run a lot faster and the picture quality is phenomenal.
I went with the Ultra version that is just under $100. There are cheaper Roku options out there but can vouch for them.
Good news! Pluto TV is now WORKING again on my big screen TV as of this morning. I wouldn’t be surprised if the Pluto TV engineers saw this thread and resolved the problem.
