I use a seagate expansion 5tb HDD on which I put my mp4 movies so I can watch them on a Samsung tv. Since yesterday, when I add movies to the HDD they show up as empty folders on my Samsung TV. All the movies I ever added before yesterday play just fine. It's only the movies that I added since yesterday that show up as empty folders on my samsung tv. The movies play perfect on pc. When I copy a movie from my seagate expansion HDD to another Seagate expansion hdd it plays fine as well on my samsung tv. Does anybody have an idea what could be wrong?
