Some old TV models lack the support for the new H.265 video codec. If your MP4 is encoded through H.265, it cannot be played on your TV and should be converted to your TV-compatible format with a video converter for smooth playback. If your MP4 have an unsupported audio codec, you should change the audio format of the video to a supported format with a video converter as well.
