Yesterday I was watching a movie I loaded on my tablet during a short flight. It worked fine then I had to pause to get off the plane. An hour later I went to finish the movie and now no video on my tablet will play through the Video Player app. It will start to load/play then just locks up. I've re-booted several times. The movies are on an external SD card so I also tried moving it to the internal memory and still nothing. I've also cleared cache and data from the video player. Also tried clearing the cache partition. Any other thoughts before i try the drastic route of factory reset?
