Hi,
My main TV in the house was a samsung tizen 2013 model, it turned out to be too much work with emby with the USB sideloading every month (no i cannot change it to be in USA zone as have NZ apps). I went and purchased a new television and stayed away from Samsung and got a Sony which is an android television.
Now none of my AVI files will play, and I have many in my libraries. 🥵
