I am using the Video app that comes with the SP. I am using it to play videos that are located on my NAS device. When I navigate to the directory that contains the videos, Win 8 does not display the names of the individual video files. It does show an icon for each video and the little "play" button but the name of the file is not displayed. If I select each unnamed file (by touching it), the system does show the name in the resulting popup. It seems to be files with the mp4 extension that have this problem. Anyone else with the same issue?
