I am watching a MP4 formated video that is stored on a local drive of the MediaPortal PC. After the video has played for about 30-60 mintues (it varies), I get the White Spinning Circle symbol that would typically indicate that something is buffering. Nothing appears to be happening, and I have allowed it to continue for as long as about 15 minutes, but I don't know if it would eventually stop or not. However, if I pause my video, close MediaPortal and then open it again and go back to the video to resume, everything works fine for another 30 minutes to an hour or so. Has anyone else seen this situation?
