Unusual Video Playback Problem!

Today in the morning I played a mp4 movies for an hour then switch the player off. Again after a while when I restarted the player and tried to play the same movie it said that “Unsupported file type. Please check the list of supported …” Again and again I tried but I couldn’t able to play that movie! But the other movies were playing fine. Can anyone tell me what could be possible reason?

Any idea / suggestion guys?

Post the Media Info of tha movie:
