Good, except…

App is great because it auto-tags tv shows and movies and a clean interface and keeps track of recently played and where you left off (just like a streaming service).
However, some video files for some reason do not stream from this app to my Samsung TV—using either air play or screen share. The same file works fine with screen share if I use VLC. The same file also plays fine in the infuse app itself (on my phone).
I get no error messages or anything. The video loading screen just exits and and the screen returns to the play video screen.
Very frustrating because I really like this app and do not want to have to use VLC to screen share certain files and I also do not want to just watch it on my phone with the infuse app. File type is mp4.
