What can I do to improve playback.
I have the following issues and it's keep me from moving over to Channels.
Some media jitters
Trailers that are automatically downloaded via Sonarr/Radarr add-on's don't always play, or they play with a black screen
Try changing the video decoder to software or hybrid. Unfortunately, there really isn't much Channels can do about this, as the hardware video decoder has limitations, and the processor isn't quite powerful enough to consistently deliver perfect playback.
There will always be a trade-off with limited devices like this.
With this in mind, and the fact I don't plan on changing my devices I'd probably be better suited to stick with Emby.
Unless I can figure out what file formats I need to make sure my media is in?
