Not sure which tv you have, but there is a webos client that works well. It’ll occasionally decide to transcode atmos stuff instead of direct streaming but restarting the movie once or twice gets it to play nice.

I don’t reencode anything, I keep the raw bdmv rip and remuxed mkv for jellyfin. Even if the difference is imperceptible, as long as I have the storage space there’s no reason to spend time fiddling with conversion when it can only make things look worse.
