Just changed my main TV from an 8 year old Plasma to a 4k 60" Samsung TV/surround sound. Moved the Apple TV 3 to another tv and purchased the latest Apple TV 4 for this tv. At the same time, I changed from cable to Fibre through Bell Canada but I am now using a much faster fibre cable than I was before. (no idea if that is important to know) 1 month in and it seems we now have to reboot the Apple TV daily. First the picture freezes, but the audio continues and a reboot is necessary, which tends to fix it, until the next time. Not happening when we watch Netflix though. I download TV shows in .mkv format, convert with Handbrake to .mp4, then load up in iTunes which shows up under Home Videos. Using Apple 3, before, to watch on the TV, I had to double click on the file IN itunes and it would then send it to the TV. That's changed with this new one and I no longer have to do it that way. Partner turns on the TV, opens up Computer on the screen, and browses the shared library and clicks on what he wants to see. Not sure what I am doing wrong with these new changes and/or how to fix them but getting tired of a freezing screen at always the most inopportune viewing moment Ideas? (latest version of Apple TV, no updates needed) T.I.A.
