but a goofy message about What DVDFab will do when saving to my Plex Media Server folder pops up. Is DVDFab downgrading the output (saved) resolution? A message pops up that was not there before. If you want me to use the PlayerFab I suggest adding it to the Plex Media Server. That is the only tool I am using to play back the 4K Ultra HD movies I purchased. If the output from DVDFab does not support 4K UltraHD for saving my movies I will find another tool. What is this message? Is DVDFab output 4K UltraHD?
